Alaska and the Soviet Invasion (T2k)

[Legbreaker]

I don't think it matters if the nukes and invasion occur in the same week. The same month would be more than enough to add to the general chaos.
Doesn't even really matter which came first - if the landing was first, then perhaps the US were already in the process of reassigning units for Alaska, but then the nukes hit. That right there could delay units hitting the field by a few days at least as their orders are changed in transit.
If the nukes came first, then a landing would only add to the general panic felt back at HQ. Already struggling to deal with the escalation and destruction of what a couple of days before were strong and victorious units, they're suddenly faced with having to deal with a whole new and totally unexpected front opening up at their back door.

All in all and no matter which way you look at it, it's a scary time to be in command. It's no wonder that a certain US president (Munson?) suffered a nervous breakdown a few months later (around Feb 98?).
