Russia Can’t Beat NATO—But Putin May Try
Can Russia defeat NATO? The answer is no. Vladimir Putins armies cannot prevail in a direct contest with the NATO alliance.
This, however, is the wrong question. The Wests more pressing concern should be whether Putin, for his own reasons, will force Russias military into a clash with NATO regardless of the consequences. The Russian president is a neo-Soviet nostalgist who not only craves revenge for the collapse of the USSR, but who still harbors old-school Kremlin fantasies about the weakness of the decadent West. If Putins adventure in Ukraine turns into an attempt to test NATO, his miscalculation will result in global disaster, and so it is imperative that U.S. and Western policy now should be to stop the Russians right where they are and to end Putins reckless gambling streak.
