Or there is the example of Soviet Missiles in Cuba.
The US absolutely will not tolerate that. That is not unusual by the way. Try putting missiles or troops in Ireland and see how Britain historically reacts. I can draw example after example. Major powers simply will not allow such encroachments by other major powers in their backyards. You can jump up and down and scream about sovereignty all you like. That ain't gonna change anything. They won't tolerate it.
You can't make Neocons grasp that no matter how you explain it. Their mentality is "us good, them bad" and they refuse to get out of that grade school mindset. Of course their foreign policy prescriptions will only lead to catastrophe.
