You know in a way this is funny.
Iran and it's little runt of a dictator pull all of this crap, the calling for the destruction of Israel, the United States, the anti-Semitic screeds, the insane drive for nuclear weapons, etc., etc., but the presence of David Duke at a Holocaust Denier's Convention in Tehran is supposed to be the straw that broke the camel's back.
There is a simple and effective answer to Iran's troublemaking, and it involves nothing more complicated than pulling a B53 warhead (yield = 9 megatons) out of our inventory and dropping it on Tabriz, and then sending a message to the little bearded wonder asking him if he'd like to keep Tehran intact while pursuing a new hydroelectric power program, as his nuke program will be on the way out.
Well fyi the B53 as now been updated with the model B61-11 though at a mere 400 KiloTon yield vs the 9,000 KiloTon for the B53 bomb and its designed as an earth penetrator instead of a strategic weapon.
