I don't know what the US leadership has on EU governments, but from their behaviour on the CIA secret flights it's obvious they think they cannot afford to contradict the US.

I am convinced "Atlanticism" is inimical to Europe's interests, but it's one thing not to join an alliance and a very different proposition to leave it. Either I am hopelessly out of touch, or on the radical fringe, or it would take the US using a nuke for anyone to even consider quitting NATO, and even then they might remain out of fear.

When's Europe going to come to my aid?

A serious answer: what kind of aid are you talking about?
