I agree that the there should not be US controlled bases in Europe, including missile defence systems... But I might support a NATO controlled one.
I think it suspect that the very place Russia wants to place a missile defence system is right next to Chechneya
sure sounds to me like Putin wants a place he can put offensive missiles to strike Chechneya without necessarily having them traced directly back to him... but that's just a thought.
Also, I'd like to express my sincerest "What the fuck?" at Russia's threat to blow up Europe if a defence system is put into place... Do we really need to go back to the cold war? It seems like that is the road Putin is charging down. Quite sad actually, I thought the world was past that childish bullshit by now, but I guess not.
