Radically eclectic thoughts (in spanish)
mentions today the threat of a Russian general to attack preventively wherever they deem necessary
. Nice bluff, but, unless they are willing to use nuclear weapons, where they still have some standing, I guess Russia has the strategic capability, not to mention resources, of, say, Sweden or Brazil.
It's not to be disregarded, of course; the problem is that, once you break the game once, throwing preventive attacks on a country, anybody can do it. So I guess that unless we want any country that can fill a couple of transport planes with grunts launching preventive attacks all over the world, it would be a good idea for the US to assume responsabilities and say "OK, we did this, but it was a bad thing".
