> if they had one Israel and the US wouldn't have bombed them

If Iran had one nuke we’d bomb them relentlessly.

Their delivery mechanisms and ground infrastructure aren’t advanced enough to guarantee launch, and a single Fisher Price nuke is not game over. Iran with the capacity to build a bomb can be dealt with now or later. Iran with an actual nuke has to be dealt with now, or else be accepted as a regional nuclear power. (Which would mean a Saudi nuke. Which would mean a Qatari nuke, and probably also Emirati nuke.)
