The problem is, how far do we go?
How far is Putting wishing to go?
Fighting Saddam's army in 2003, the insurgency afterwards and the Taliban in Afghanistan has in no way prepared us for fighting a well equipped and trained Force, all without having the luxury of air supremacy.
Oh, and they have nukes.
IMHO, we are heading for a slightly warmer cold war hoping that we don't blink first.
