Having something hover over your head for years becomes wearying (Sword of Damocles). I hope Trump takes counsel with himself and conclude, "This just can't go on. The end must arrive. I don't want to do it, but it must be done."

I keep returning to the conviction that this must be concluded as a religious battle. Warn the Holy City of Qom to evacuate. Again. And again. Then target it with a ground-burst nuke. When the cloud blows away, leaving a permanent crater, make a point to the imams and all the world at large that they are accursed of Allah, and this is the proof, at the hands of a Christian. Allah does not protect them, does not accept their sacrifice, and will consign them to perdition if they continue in their false faith. (mic cut)

Then it will depend on whether they will be as stubborn as Japan, to require a second shot (maybe in view of Teheran) to convince them Trump is still in Allah's favor, de-legitimize the mullah-ocracy, and demoralize the IRGC.

Do you think Harry Truman would have any hesitation? Japan was every bit as fanatical, dedicated, and world-menacing as Iran...if not more so. Imagine Imperial Japan with nuclear weapons. (So much controversy about his decision, but I think it was profoundly clear and simple: "Now that we have this weapon, there is no reason for even one more American soldier to die in this war. Let the Japanese do the dying.")
