Mmmm. Id keep it around till the end of the world then just blast the last part of goverment left around.
to be honest, i would use it and its tracking device to find all the other nukes within the world, and then gather them up, and fly them off to the far eastern corner of the universe. never to cause any harm
i'd sell it to the highest bidder. The hell do i need a nuke for? I don't wanna cause anyone harm, directly. If i just sell it, then i won't be DIRECTLY responsible for anything. plus i'm sure i could get some nice dough for it.
I'm pretty sure the Christians love Jerusalem too. Fuck it even more reason, I get to troll the top 3 major ones.
