Exactly. There is irony for those who have historical perspectives. NATO for many years insisted it needed a nuclear deterrent policy because it was conventionally weaker than the Soviet Union of the day and the Warsaw Pact. Now the same logic is being reversed, and Moscow says it feels it has to hold on to its nuclear forces because it is conventionally weaker than NATO, and objectively, that's the case.
At the same time, I don't think that should be accepted without efforts to build the level of confidence that would enable those remaining nuclear forces to come down and for cooperation to be sustained. We have to appreciate what an incredible strategic accomplishment, particularly the European arms control and disarmament regimes, were in limiting the forces and the potential for war.
Of course, political changes of great significance went along with that, but there was a whole regime of notification, of observation, of restraint largely put under the limitation of specific weapons systems, eliminations of whole categories of ballistic missiles, for instance, in the INF Treaty. These are very important, a key that we have to continue to reinforce, and indeed to expand upon. That's why I emphasize a need for an active diplomacy regarding Russia on these matters and others.
