Mutually assured destruction

My question is: are either/both of these actions resolvable in GURPS? It seems that because of the granularity of turns that it's not, but I'd be interested in being proven incorrect.

Despite the expert answers given above: no.
Defensive Attack/ Cascading Wait/ Who Draws First does resolve the combatants mutual destruction but not their decision to not attack.

I think that'd come under Common Sense (Active) and the GM tells you "If you go ahead with this attack, you're practically guaranteed to get pawned."
