My view is that if Iran tries something like that, they should lose their 3 biggest cities. From orbit. Just to be really sure. Then take out one city a week until they really truly unconditionally surrender, and the IRGC formally request that a new Shah be put in place to lead a secular government. Say it. Say it like you mean it. Or keep losing cities. From orbit.
That’s similar to what I’ve been advocating for some time: destroy one of Islam’s holy sites for every act of terrorism. Supposedly their worst sin is failing to protect those sites.
