Nuclear Exchange Sort Of

I dreamt that Russia and the United States got into some kind of pissing war over something in the Bearing Straight, or maybe even north of that, maybe over oil, maybe some other resource, maybe just general territorial disputes, I'm not sure. Russia detonated a large nuclear bomb above ground over their territory as a kind of threat, like, see we have this mega-powerful super-H-bomb. The United states then followed suit detonating a big nuclear bomb above Alaska in a remote area. Then the Russians detonated three bombs as if to say "we have a bunch of these back down", then the US detonated a series of them sequentially with the rhythm of the Star Spangled Banner as if to say, "Not only do we have a whole bunch of these but we have very exact control over how or where we detonate them."

Neither country actually nuked the other country except that the detonations were done above ground and near enough to be in visual range so there had to be some radiation effects and fallout. I woke up after that, so I don't know if it would have escalated to actually tossing nukes at each other or not.
