A Bold New Baltic Strategy for NATO

The security environment has changed, so should the methods of deterrence.

U.S. security policy in North Central Europe is based on deterrence by punishment. As in the rest of its global alliance network, American extended deterrence in this region functions on the premise that the United States will be able to defeat the local challenger through devastating counterattacks. As for U.S. allies in Asia-Pacific and the Persian Gulf, the credibility of guarantees to Poland and the Baltic states has rested on the wide supremacy of U.S. military power—not only its large strategic nuclear arsenal but the “overmatch” that U.S. conventional capabilities have been thought to provide in counterattacking any aggressive move. Even more than in other regions, however, the viability of U.S. security in the Baltic has been based on faith in these abilities as, uniquely among U.S. frontier allies, the United States has not maintained even symbolic troop presences in countries east of Germany. Given the parlous state of the Russian military and the vast superiority of NATO, it has been assumed that this setup, involving retaliation in its most unsubstantiated form, would be sufficient to secure the vulnerable states of this region well into the twenty-first century.

This is no longer a safe assumption. The North Central European security environment has evolved in dramatic and unexpected ways that pose significant challenges for the continued solvency of a punishment-based deterrence. First, the local rival’s military is proving to be better armed and led than we anticipated. Long discounted as backward, the Russian armed forces under Vladimir Putin have undertaken major technical and tactical improvements and incorporated important lessons from the Georgia War. The Kremlin has pursued a multi-year, $700 billion defense modernization program that is bearing substantial fruit in Russian military operations in Syria. Its forces outstrip in size and quality any force between itself and Germany, outnumbering NATO’s CEE militaries, combined, by 3:1 in soldiers and 6:1 in planes. In the Baltic region, it has a 10:1 edge in troops and maintains air dominance over NATO’s northeastern corner.

Meanwhile, the forces that the United States would need to draw upon to correct these imbalances are shrinking. U.S. defense structures have been cut to their lowest levels since before the Second World War. In Europe, they have dropped from 300,000 troops to 60,000. The Obama administration has accelerated this process, removing fifteen bases and the most combat-ready units, including two Brigade Combat Teams (BCTs), two air squadrons and all remaining U.S. heavy armor. These drawdowns mean that CEE will continue to be characterized by unfavorable force ratios for the foreseeable future.

Second, Russia is developing tactics for evading retaliatory deterrence. The limited-war techniques used in eastern Ukraine consist of “jab and grab” land incursions designed to avoid the traditional triggers of NATO’s Article 5. These techniques operate below the threshold of deterrence by punishment and seek to create territorial faits accomplis that lower the costs of revisionism. Russia backs its stealthy battlefield methods with a tactical nuclear arsenal that exceeds that of NATO by a 27:1 margin, deployed under a doctrine of limited strikes for strategic effect. The combination of limited war and escalate-to-deescalate nuclear warfare poses serious problems for deterrence by punishment. It makes aggression less identifiable (and therefore punishable) while wresting away the presumption of escalation dominance upon which effective retaliation is based. In a limited-war setting, punishment quickly morphs into compellence: not just dissuading an enemy, but dislodging him. This shifts the psychological burden of conflict—fear of retaliation—away from Russia and places it on the shoulders of NATO—fear of escalation. It puts the latter in the position of perpetually under-responding to ambiguous provocations (and thereby losing control of strategically vital spaces by default) or over-responding (and risking war).


Doubling Down on Punishment

So far, America’s response to the erosion of its security mechanisms in North Central Europe has been “double down” on deterrence by punishment. The effort to provide strategic reassurance to the Baltic states and Poland through the deployment of U.S. trip wires represents an attempt to strengthen the trigger mechanisms of retaliation. Similarly, the designation at the Wales NATO Summit of faster response forces is, at heart, an effort to improve the West’s capacity for effective retaliation after an attack has already occurred. Such measures are likely to yield some positive results. The problem with both is that Russian techniques have rendered the very premise of effective punishment invalid. “Little green men” can go around the U.S. infantry company meant to serve as a trip wire. Crimea-style tactics can seize territory in minutes and hours, while even the fastest reaction units require days.
