That's not a new problem, though. They get the same effect nuking the place where the Football is.Another problem: All the KGB needs to do is figure out who it is and they are basically guaranteed victory. Figure out where the guy is going to be. Take the location out with a suitcase nuke. Now launch. The codes are gone, we can't fire back.
No, because the football isn't the only copy of the codes. Nuke the football and the VP issues the launch orders. Get him also and IIRC it's the Speaker of the House that gets to push the red button.
Note, also, that by their very nature boomers aren't subject to launch codes in the first place. If a boomer finds that we've been blown to bits they can launch on their own without any orders from Washington.
