Iraq was attacking its neighbors every couple of years, Iran is not.
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?
