Godde had this window of opportunity where he had two nukes and noone had anti, and he knew this because he scouted a minute before that.
It lasted around thirty seconds.
Then the rest of the game happened.

Also I didn't expect PetTurtle to get the first anti-nuke lol.

I thought the very purpose of that early nuke strat was to kill off Dein, and the second missile was there to kill both his spots at once?

I would support a command with the functionality you just suggested. Firestate seems to dangerous, as you may select the antinuke accidentally along with other units.
