The military assets need to be destroyed. Even though the sanctions are hitting their finances it doesn’t take any money to push a button on a weapon that’s already made and deployed. Iran has thousands of cruise missiles some of which have >1200 mi. range.
And they’ve threatened to restart uranium enrichment.
It is a no brainer, but I have to say they have seen this coming a long time, i am sure we have insurgents here, and by the way things are I expect a nuke to be slipped to somewhere Iran can claim it’s detonation by Nork etc
