Rule 2: In order for Rule 1 to kick in, I would have to KNOW, not simply be assured by the government, that it was in fact necessary and not simply a power play by a government bent on dominating their erstwhile masters and taking away any means they might have to defend themselves against that domination.
I can't imagine the circumstances under which rule 2 could EVER be satisfied.
Foreign nukes falling from the sky would satisfy me for rule #2, but I can't imagine it mattering after that.
