Nuclear Gunfighting

Can you tell me the last time we got into gunfights with a county that (a) also had nuclear weapons and (b) was supposed to be one of our friends?

Well, we are now doing just that.

The story makes no sense, as it says that the Afghan and American troops were a "mile and a half" away from the border when the exchange of fire with the Pakistani troops took place. They were exchanging small-arms fire at a range of 3,000 yards?

They might as well have been waving their dicks at each other. Or we are not being told what really happened.
