Iran has shown that it is remarkably sane actually, given the aggression shown towards it by Israel and the US and has made a lot of efforts to reach a deal.
Remember, it was the US that exited the JCPOA and now it wants Iran to give up all its misses so that they would be defenseless.
I have no love for theocracies, but I do think the Iranian system is a lot better than the likes of Saudi Arabia, which we're buddy buddy with.
Oh and I guess the founder of Syrian branch of AQ and deputy head of ISIS running Syria is better that what was before too, in your book?
