Getting Another War On

Krauthammer this morning goes into raptures about the possibility of reliving the 1970s and 1980s:

The most crucial and unconditional measure, however, is this: Reaffirm support for the Saakashvili government and declare that its removal by the Russians would lead to recognition of a government-in-exile. This would instantly be understood as providing us the legal basis for supplying and supporting a Georgian resistance to any Russian-installed regime.

This is a 1980s Afghanistan gambit, a de facto return to the Cold War, even though Russia is not a global expansionist power any more, and even though it is no longer communist. No thought given, apparently, to the chance that this could backfire on a power now occupying two countries rather closer to Russia than Georgia is to the US. Oh, well. They'll figure that out later. There's Russians to fight!

One thing that baffles me: why does the US need a legal basis for anything in Krauthammer's view?
