How the West Failed Ukraine and What We Can Do
The war in Ukraine is frequently described in Western discourse as a humanitarian crisis and as a defence of the international legal principle that borders should not be altered by force. These descriptions are accurate, but incomplete. They identify important moral and legal dimensions of the conflict while leaving underdeveloped its central strategic significance. Ukraine is not only a victim of aggression. It is also the principal site at which the credibility of Western deterrence, the durability of Europe’s post-Cold War security architecture, and the future costs of Russian revisionism are being tested.
A more adequate framing would treat the war primarily as a problem of containment. The question is not simply whether Ukraine deserves assistance, though it plainly does. The question is whether Russian territorial revisionism can be made sufficiently costly that future coercive action against Ukraine, Moldova, the Baltic region, or other exposed parts of Europe becomes less attractive. This distinction matters because humanitarian arguments are vulnerable to fatigue, whereas security arguments clarify the relationship between assistance to Ukraine and the defence of Western interests.
The failure of Western policy has not been one of complete inaction. The United States, Britain, the European Union and several individual European states have provided significant military, financial, diplomatic and intelligence support to Ukraine. The problem is instead that Western policy has often been reactive, incremental and constrained by an excessive fear of escalation. This has produced a persistent gap between the stated objective of resisting Russian aggression and the instruments deployed to achieve that objective.
The origins of this failure predate the full-scale invasion of February 2022. They can be traced at least to the 1994 Budapest Memorandum, under which Ukraine agreed to relinquish the nuclear weapons it inherited after the collapse of the Soviet Union in exchange for security assurances from Russia, the United States and the United Kingdom. It would be misleading to treat Ukrainian denuclearisation itself as the error. Given the weakness of Ukraine’s nuclear command-and-control arrangements, the technical dependence of the inherited arsenal on Russian systems, and the wider proliferation risks associated with a newly independent state possessing a large Soviet nuclear stockpile, the removal of those weapons was a defensible and arguably necessary policy objective.
The weakness lay in the security architecture that replaced them. The Budapest Memorandum contained commitments to respect Ukraine’s sovereignty and existing borders and to refrain from the threat or use of force against it. It did not, however, provide Ukraine with a binding defence guarantee. The United States and the United Kingdom assumed political obligations, but not obligations equivalent to those created by an alliance treaty. The result was a significant asymmetry: Ukraine surrendered a form of strategic deterrence, albeit one it may not have been able to control safely or sustainably, while receiving assurances that were not backed by automatic enforcement mechanisms.
This was a strategic misjudgement by Ukraine, which should have sought more reliable guarantees, but it was also a failure of American and British statecraft. Russia had been the principal adversary of the United States and its allies for much of the twentieth century. Its weakness in the early 1990s did not make its future strategic posture predictable, nor did it eliminate the possibility of renewed imperial or revisionist tendencies. A prudent settlement would have recognised that Ukraine’s long-term security problem was not solved by denuclearisation. It was transformed by it.
The Budapest settlement therefore had consequences beyond Ukraine. It weakened the perceived credibility of security assurances as instruments of non-proliferation diplomacy. States considering whether to relinquish strategic capabilities will reasonably distinguish between assurances and enforceable guarantees. The lesson they may draw from Ukraine is not that nuclear disarmament is always irrational, but that security assurances from major powers are inadequate when they are not accompanied by credible mechanisms of deterrence and response.
The second major failure occurred after Russia’s annexation of Crimea in 2014. Crimea should have produced a comprehensive reassessment of Western policy towards Russia. Russian forces and affiliated personnel in unmarked uniforms enabled the seizure of Ukrainian territory while Moscow denied responsibility in ways that were transparently implausible. The operation demonstrated that Russia was willing to exploit ambiguity, use force below the threshold of formal war, and test Western willingness to impose costs.
A more coherent response would have included several elements: lethal military assistance to Ukraine; expanded intelligence, surveillance and reconnaissance support; secure communications; accelerated Ukrainian force modernisation; a substantial reduction in European dependence on Russian energy; and sanctions designed to impose structural costs rather than merely signal disapproval. Instead, Western governments responded with a mixture of sanctions, diplomatic condemnation and continued economic accommodation. These measures imposed some costs on Russia, but they did not amount to a strategic reset.
It is important to distinguish here between military caution and economic accommodation. After 2014 there were genuine reasons to avoid direct military escalation with Russia. A nuclear-armed adversary cannot be treated as an ordinary regional power, and the risks of inadvertent escalation were not imaginary. Responsible decision-making required attention to escalation dynamics, alliance cohesion, domestic political constraints and the limits of Western public support. The problem is that this caution in the military domain was too often extended, implicitly and unjustifiably, into the economic domain.
There was little strategic justification for maintaining, and in some cases expanding, economic dependence on Russia after Crimea. This is where comparisons with Neville Chamberlain can be misleading. Chamberlain’s appeasement was strategically disastrous, but his motives were shaped by the memory of the First World War, by Britain’s military weakness and by a sincere, if mistaken, desire to avoid another continental war. The post-2014 accommodation of Russia had a different character. By then, Russia’s willingness to use force in its near abroad had been demonstrated in Georgia and Ukraine. The relevant information was available. The risk of dependence was visible. Continued commercial engagement therefore appears less like tragic caution and more like the prioritisation of economic convenience over strategic adjustment.
This point is particularly important in assessing Germany’s role. Germany’s dependence on Russian energy was not merely a commercial fact. It was a strategic vulnerability. After 2014, Berlin should have treated that vulnerability as a central security problem. Instead, Germany continued to support or tolerate arrangements that deepened energy dependence, including the Nord Stream framework. This policy reflected a belief that economic interdependence could moderate Russian behaviour, or at least remain insulated from security competition. After Crimea, that belief became increasingly difficult to sustain.
Merkel’s defenders can plausibly argue that she was cautious and that caution was not inherently irrational. They cannot plausibly argue that the relevant information was absent. By 2014 Russia had invaded Georgia, used energy as a political instrument, suppressed domestic opposition and seized Ukrainian territory. Leaders make decisions under the influence of experience, motive and information. In this case Germany possessed both experience and information. The persistence of economic accommodation therefore raises serious questions about motive, including the role of industrial interest, cheap energy, coalition politics and institutional inertia.
The United States also failed to adjust sufficiently after 2014. The Obama administration did not ignore Ukraine, but it treated the crisis as something to be managed rather than as the first stage of a broader Russian challenge. Its hesitation over lethal aid, its emphasis on diplomacy without adequate coercive leverage, and its concern about escalation reflected an underestimation of the degree to which Russia had already revised the strategic environment. The relevant question was not simply whether Western action might provoke Russia, but whether insufficient Western action would encourage Russia to infer that the costs of further coercion would remain tolerable.
This mattered because deterrence depends not only on formal commitments but also on observed behaviour. Adversaries draw inferences from hesitation, delay and ambiguity. The United States did not communicate indifference, but it did communicate reluctance. For Ukraine, that reluctance increased insecurity. For Russia, it supplied information about the likely limits of Western response.
Between 2014 and 2022, Western policy thus contained a persistent contradiction. Russia was sanctioned, but not strategically isolated. It was condemned, but not treated as a state whose conduct required a fundamental reassessment of economic and security relationships. Commercial normality continued in parallel with political disapproval. This contradiction reduced the deterrent value of Western policy because it showed that Russia could absorb penalties while preserving significant channels of engagement with Europe.
The full-scale invasion of February 2022 finally produced a much larger Western response. Ukraine received substantial military, financial and intelligence assistance, and some of this assistance was operationally significant. Yet even then, Western policy retained the incremental character that had marked earlier responses. A capability would often be defined as too escalatory, debated for an extended period, approved only after battlefield necessity became more obvious, and then delivered late, in limited quantities, or with restrictions on use.
This pattern was visible across multiple categories of assistance: anti-armour weapons, rocket artillery, longer-range strike systems, main battle tanks, combat aircraft, air defence and intelligence support. The issue is not that Western assistance was irrelevant. It was not. The issue is that assistance was often sequenced in ways that limited Ukraine’s ability to plan coherently and act at scale. A military strategy cannot be built efficiently around capabilities that may arrive late, arrive with political constraints, or arrive only after operational windows have closed.
The costs of delay in war are not abstract. They appear in lost territory, depleted ammunition, damaged infrastructure, exhausted units and the opportunity afforded to the adversary to adapt. Russia used time to entrench, disperse assets, alter logistics, harden positions, expand defence production and revise tactics. Incremental Western support therefore had a dual effect: it helped Ukraine survive, but it also reduced the possibility that assistance would arrive early enough and in sufficient concentration to change the strategic trajectory of the war.
This reflects a broader problem in Western escalation management. Western governments have repeatedly treated Russian escalation as the principal risk to be avoided, while giving insufficient weight to the risks produced by Russian success. A policy that minimises immediate escalation risk can increase longer-term systemic risk if it teaches an adversary that persistence, coercion and nuclear signalling are effective tools for limiting Western action. Escalation management is necessary, but it is not synonymous with restraint. It requires a theory of how to shape adversary expectations, not merely a habit of avoiding difficult decisions.
Intelligence support illustrates the same tension. Western intelligence assistance has been of substantial value to Ukraine, but it has also been shaped by legal and political constraints. Some of these constraints are legitimate. Direct, real-time targeting support can raise difficult questions under international law and alliance policy. However, the broader dependence of Ukraine on externally controlled intelligence systems creates vulnerability. Where access to satellite imagery, tasking priorities or intelligence channels can be modified by political decision, battlefield capacity becomes partly contingent on the domestic politics of external states.
This has implications for Europe. European states possess meaningful intelligence, surveillance and reconnaissance capabilities, including national satellite systems, synthetic-aperture radar assets, airborne early-warning platforms and signals intelligence resources. Yet European capacity remains fragmented and insufficiently dense. The war has exposed the limits of a security architecture in which Europe’s strategic awareness and operational support remain heavily dependent on the United States. If Europe wishes to possess a more autonomous capacity to respond to threats in its own theatre, it must invest not only in platforms but also in integration, tasking, dissemination and wartime decision processes.
The tendency to treat Russia as a problem confined to Ukraine is another analytical error. Russia is the most direct military and political threat to European security. This does not imply that a conventional Russian invasion of Western Europe is imminent. Rather, it means that Russia employs a wide range of coercive tools against the European order: nuclear intimidation, cyber operations, sabotage, political financing, disinformation, energy leverage, maritime pressure, assassination attempts and other grey-zone activities. These instruments are not secondary to Russia’s strategy. They are central to it.
The Baltic region, the Black Sea, Moldova, the Arctic approaches and the European information space all form part of this wider contest. Russian activity around Kaliningrad, its interest in pressure against Finland and the Baltic states, and its use of electronic warfare and political subversion should be understood as elements of a broader coercive posture. Moscow does not need to initiate general war in order to weaken European security. It can test cohesion, exploit ambiguity and raise the political cost of collective response.
For the United States, Europe is not a peripheral theatre. It remains central to the Atlantic security system. A Europe vulnerable to Russian coercion would impose costs on American strategy, reduce allied capacity, complicate deterrence in other regions and embolden adversaries who study Western alliance behaviour. The case for aiding Ukraine is therefore not reducible to sympathy for Ukraine. It is also a case about preventing the degradation of a security system from which the United States and its allies have benefited for decades.
The effect of American domestic politics on this system is significant. A sharp reduction in American military support for Ukraine, or rhetoric that appears to validate Russia’s interpretation of the war, does more than weaken Ukraine materially. It alters the information environment in which adversaries assess American reliability. Authoritarian states observe whether American commitments can be reversed by partisan change, whether alliances can be divided by domestic political incentives, and whether sustained pressure can outlast democratic attention.
China is particularly likely to draw lessons from Ukraine. It will not simply replicate Russian errors. It will study the failures of Russian logistics, the difficulty of conquering a mobilised society, the importance of drones and electronic warfare, and the industrial demands of prolonged conflict. It will also study Western behaviour: delays in weapons delivery, shortages of munitions, alliance disagreements, escalation anxiety, sanctions design and the durability of public support. Deterrence is not confined to a single theatre. States update across cases, especially when assessing the credibility and operational coherence of rival coalitions.
Iran adds a related, though distinct, dimension. American military power remains formidable, but tactical capacity is not equivalent to strategic coherence. Military action that is poorly integrated with alliance consultation, regional objectives or a clear political end state can demonstrate capability while also revealing deficiencies in strategic design. For adversaries, the relevant question is not whether the United States can employ force, but whether it can align force with durable political objectives and alliance management. The war in Ukraine is therefore part of a larger pattern through which adversaries evaluate Western decision-making under stress.
A more coherent policy would begin by recognising that support for Ukraine is not charity. It is a form of strategic insurance. Assistance should be increased, and unnecessary restrictions on its use should be removed where they reduce Ukraine’s ability to impose military costs on Russia without producing offsetting escalation-management benefits. The objective should be to improve Ukraine’s ability to defend itself, degrade Russian military capacity and reduce the probability that Russia concludes aggression can produce durable gains.
Europe must also expand its own capacity for intelligence support, defence production and military readiness. This requires more than higher headline defence spending. It requires munitions production, drone manufacturing, counter-drone systems, electronic warfare capacity, resilient communications, air defence, hardened logistics, medical surge capacity, civil defence and the institutional mechanisms necessary for rapid procurement and deployment. European rearmament should be measured not by announcements, but by stockpiles, production rates, readiness levels and operational integration.
Sanctions policy also requires greater coherence. Measures that impose costs while leaving major evasion channels open have limited strategic effect. Secondary sanctions should be considered against firms and states that materially support Russia’s war economy or facilitate circumvention. Such measures carry costs and should be designed carefully, but a sanctions regime that does not address evasion becomes progressively less effective over time.
Russian influence operations within Europe should be treated as part of the security problem rather than as a separate law-enforcement nuisance. Political financing, covert media activity, corruption networks, organised crime links, front organisations, sabotage cells and abuse of diplomatic or consular cover all contribute to Russia’s ability to weaken European cohesion. Countering these activities requires intelligence coordination, legal tools, financial transparency and political willingness.
There is also a case for NATO states to provide more extensive rear-area assistance to Ukraine. This need not involve combat units at the front. It could include training, maintenance, logistics, medical support, repair capacity, drone production assistance and planning support. Such measures would improve Ukrainian battlefield effectiveness while remaining distinguishable from direct combat participation. The purpose would be to reduce the operational gap between Western capability and Ukrainian need.
At the same time, Western governments should avoid assuming that Russia’s failures in Ukraine imply long-term strategic incapacity. Russia failed to achieve its initial objectives, but it has adapted. It has mobilised resources, revised tactics and continued to exploit advantages in artillery production and tolerance for attrition. Future conflict in Europe would likely be drone-intensive, electronically contested, ammunition-heavy and logistically demanding. A serious European security policy must therefore plan for industrial war, not merely for small expeditionary operations or symbolic deterrent deployments.
The broader lesson is that Western policy towards Ukraine has suffered from a repeated mismatch between stated objectives and chosen instruments. In 1994, Ukraine’s denuclearisation addressed an urgent proliferation problem but did not create a robust security architecture. In 2014, Crimea revealed Russia’s willingness to revise borders by force, but the Western response did not fundamentally alter the strategic relationship. After 2022, Western assistance helped Ukraine survive, but the incremental and constrained nature of that assistance limited its strategic effect.
The war should therefore be understood not only as a Ukrainian struggle for survival, but as a test of whether Western states can align moral claims, legal principles and strategic interests with adequate instruments of policy. The central issue is not whether the West possesses sufficient aggregate power. It is whether that power can be organised coherently, applied in time and sustained long enough to shape adversary expectations.
Failure in Ukraine would not remain confined to Ukraine. It would affect European security, Western non-proliferation diplomacy, the credibility of security assurances, and the calculations of adversaries in other theatres. Conversely, a policy that enables Ukraine to resist successfully and imposes substantial costs on Russian aggression would strengthen deterrence beyond the immediate conflict.
The task, then, is not to abandon escalation management, but to embed it within a more serious theory of deterrence. Restraint has value when it preserves room for manoeuvre and prevents unnecessary war. It becomes self-defeating when it persuades an adversary that coercion will be rewarded by caution. Ukraine is the case in which the West must demonstrate that it understands the difference.
