The tension is heading in that direction, but the reasons aren't even close to the Cuban Missile Crisis. We aren't secretly basing tactical nuclear tipped missles in Poland. We're openly installing an anti ballistic missle system that not only protects most of Europe, but Moscow as well from threats to the south (Iran). Our interceptors don't even have an explosive warhead. They use a kinetic energy kill vehicle that is designed to destroy an incoming warhead by running into the thing and smashing it to pieces.
Poland is also getting Patriot IV missile systems as well for defense against tactical missile systems (Russia).
Again Russia is just pissed because all the countires they controled back when they ran the USSR, are seeking entrance into NATO for protection from Russia. Guess 50 some odd years of being trampled on by mother Russia was enough for most of them and they are doing what they have to do to make sure it never happens again. Seeing what has been going on in Georgia is only reinforcing those beliefs. Not to mention hearing a Russian General Officer going on TV and saying that an attack against Poland is likely and that there could be a nuclear element involved, doesn't help matters either.
The boys in Moscow need to take a real hard look at Putin. They've made some real progress in joining the world community over the years and Putin is trying real hard to toss it all away. Only this time the big bad bear, doesn't have the claws and teeth it once did. Rattling the nuclear saber this early in the game proves that beyond a doubt.
Russia has absolutely nothing to gain by taking this line, but they sure do have allot to loose, and I'm not talking about Putin and his cronies, I'm talking about the Russian people in general. They really need to wake up to what their "leader" is doing.
