The Russo-Ukrainian War may soon produce a major U.S.-Russian nuclear crisis. Despite President Joe Biden’s occasional cautionary remarks that he understands the risk of nuclear escalation in the event of a direct clash between U.S. and Russian forces, there are other ways that a very dangerous moment can emerge. Widespread optimism about our ability to avoid such an outcome depends greatly on the assumption that both sides are very cautious where nuclear weapons are concerned and have assimilated that caution into their conduct of the war. This is false.
The critical tools for the avoidance of escalation of any war are the limitation of ends and the limitation of means. These tools are disappearing fast. It is apparent from leaks in several media outlets that the United States is itself deeply involved in the Ukrainian war effort. We are providing billions, and soon tens of billions of dollars in military assistance, and this assistance seems likely to involve ever more sophisticated and longer-range weapons. We are providing the Ukrainians with intelligence to support defensive and offensive operations, such as the sinking of a major Russian warship. Even the defensive intelligence assistance has supported provocative actions. Russian officers at the front are legitimate and useful targets for Ukraine, but not for us. Yet, the United States has apparently assisted these efforts.
Ukrainian forces seem to be raiding across the Russian border. From a strictly military point of view, this makes sense. From the point of view of escalation control, this sacrifices a critical and useful firebreak. Russia does not raid Ukraine’s sources of resupply across the border of NATO countries; Ukraine should not raid the Russian army’s source of resupply in Russia. It does not help that senior British officials have applauded the idea of these raids. Russia’s sponsorship of assassination attempts on British soil certainly deserves some payback. Britain has gotten its payback through the extraordinary tactical success of the anti-tank guided missiles they have supplied to Ukraine. The British, of all people, should remember the meaning of “a bridge too far.”
