On predicting Russian appetite for nuclear escalation.

Whether Russia has a lowered nuclear threshold is a matter of perspective. Moscow sees nuclear weapons as essential for deterrence and useful for nuclear warfighting in regional or large-scale war. That is hardly a recent development, though it may be new to decision-makers in the United States. There is an erroneous perception in American policy circles that at some point Washington and Moscow were on the same page and shared a similar threshold for nuclear use in conflict. It is not clear that this imagined time period ever existed, but perhaps both countries viewed nuclear escalation as uncontrollable, or at least publicly described it as such during the late-Cold War period. In principle, Russian leadership does view nuclear use as defensive, forced by exigent circumstances, and in the context of regional or large-scale conflicts.
