Is that "would no longer exist" or "I hope would no longer exist"? Because you really really like repeating existential threats to Iran. In any thread about the US military adventures you feel the need to remind us of how US could kill everyone.
I shouldn't dignify this stupidity with a response, but I don't have any ill will towards the Iranian people, nor do I support this escalation at all. But it doesn't need to be explained what would happen to Iran if they directly attacked the US or assassinated the President - which was my response to that being mentioned in the post I quoted.
