Removed but I thought the East didn't get attacked.
There were two nukes on the East Coast, that I can remember. One was apparently a one-off sub launched missile* that was fired just off the coast and hit D.C. The second was planted on a barge on, I think the East River, and nuked Manhattan. I do know Columbia University got hit/destroyed by the blast, but I honestly don't remember which Borough it had been in.
For the Midwest, Kansas City, I think it was, got hit, due to being a major crossroads city, along with SAC Headquarters in Omaha, Nebraska. I assume several of the ICBM Fields got hit, but there weren't actually many nukes used on the North American Continent during the War. There are repeated, unconfirmed stories**, about another potential nuke carried by a Spetznaz Team which was targeting Mount Weather, where Bush might have been. It's been confirmed, publicly, that there was a Spetznaz attack on the mountain, but there's only unconfirmed speculation on whether or not there was a nuke. All we know for sure, was that shortly after that raid, we openly nuked a couple of command bunkers in Russia.
There was also a nuke fired by a Royal Navy Boomer Sub, when Argentina was ramping up another attempt at taking the Falklands. They did hold off on launching in order for us to send a guy down to try to talk them out of invading the Falklands, but the attempt failed, and so the Brits nuked the harbor/port where the invasion fleet was gathering.
* - There was actually some debate over this over on the old, old board, due to the initially planned option, of a sub launched cruise missile not actually existing at the time. I can't remember exactly what the decision about it was, but it was either a special one-off missile, or a SLBM launched at a very low trajectory, to hit D.C.
** - Spoiler: There was actually a story on the old, old Board, talking about the War in the Southwest, and it included a segment where Adam Lodge was questioning a DGI Illegal, who caught got running agents. He showed her the news report on the raid, followed by the reports on us nuking Russia and basically walked her through why we had nuked Russia. It was part of him turning her, pointing out that we had nuked Russia in retaliation, with no response from them, and Cuba was working really hard to really piss us off, like the Russians had done.
Edit: I added the first "*" Section, explaining the history behind the D.C. Missile Nuke.
