Russia’s war on Ukraine is poised to bring into being a new European security order. Although the last eight months have been full of surprises, that new order may very well be marked by unstable standoffs, buildups, and dangerous activities and incidents between both Ukraine and Russia and Russia and Ukraine’s Western backers. These will risk ever more dangerous crises, all with the threat of nuclear war looming. The last eight years of military deployments, near-simultaneous exercises, and other proximate activities by Russia and NATO offer some hints as to what this future may look like. These, notably, were undertaken not to prevent an escalation in Ukraine but to deter NATO from attacking Russia and vice versa. During this time, discussions about a return to conventional arms control in Europe to mitigate the dangers of military activities gained little traction with policymakers, and the agreements and arrangements that had been in place continued to deteriorate and dwindle. In late 2021, as Russian forces massed on Ukraine’s borders, the West offered Russia a return to conventional arms control solutions. Russia countered with demands that NATO return to its 1990s-era force posture and eschew any further enlargement, and then proceeded to roll its tanks into Ukraine. During the tense months prior to Russia’s invasion, the conventional arms control mechanisms that remained, such as the Vienna Document, made it possible to call out Russia’s buildup, but not reverse it or prevent attack. Although there is little logic and less appetite for new arms control deals now, an end to fighting in Ukraine will create new imperatives to make Europe safer than it is today. While sanctions can limit Russian capacity to some extent, they may well be inadequate to prevent substantial buildups. For this reason, NATO members and their partners should be thinking in advance about how they could limit Russian capabilities via negotiated arrangements with robust verification measures and repercussions for violations. Once the shooting stops in Ukraine, deals such as these could make a more secure Europe, bolstered by more reliable deterrence, attainable.
