That would likely provoke a war with Iran, and even then, he wouldn’t be able to do that without bipartisan support. If he can do that, and it can be proven Kamala would not, that is tangible evidence of escalation, something everyone else here failed to provide in any capacity, thanks.
Still, again, I question his ability to actually accomplish that even if he wanted to, and question that under conditions that allow him to be able to that Kamala would not also go through with it, given her record of unconditional support for genocide.
