Say you are the US, you are at +17 VP, and Defcon is at 2. You event Duck and Cover. This event says "Degrade Defcon 1 level, then US player earns VPs equal to 5 minus the current Defcon level". Do you win or lose or does the game end in a draw?
Surprisingly this doesn't seem to be in the rules, which say:
The instant one player reaches a score of 20 VP, the game is over and that player is the winner.
...
A player may also win the instant his opponent causes the DEFCON level to reach 1.
