Agreed. If the IRGC is able to negotiate some form of staying in power (any form) we will just be kicking the can down the road. Sure, we bombed them back to the stone age, but we will have to do it again sometime in the future.
Exactly. This is why Trump has stated specifically, on more than one occasion, that he would not leave this task to future presidents.
The Islamic regime will not be allowed to stay in power. Whether this is done through negotiation, an army of Iranians in the streets, or divine intervention, I really don't care. The IRGC must and will be removed from power in Iran.
