Re: Well oil sure believes Iran will be mad.
Iran's major problem is thier economy is doing very poorly and its population is already obviously getting tired of this state of being.
China is thier remaining major material backer and should the Iranians go real deal and start making oil go up (openly use antiship missiles on third party tankers, use ballistic missiles on population centers, etc) the Chinese will be very..Very..VERY unhappy. China cannot afford 90 dollar brent right now. I think this is what prevents a greater escalation as the Iranians will disintegrate even faster without China.
Meanwhile for all his myriad flaws Trump seems to not take any bait from the Iranians militarily and is slowly strangling the regime as it spends its increasingly limited money supporting zero return efforts in Syria/Lebanon, Yemen and on nuclear weapons to protect itself from an invasion that will never be launched by anyone.
In short other than terror operations that achieve no goal (what did Iran get for attacking the troops and embassy in Iraq) what can Iran do?
Just as Saudi Arabia was struck in a massive open act of war by Iran but was not in the position to do much about it, now that shoe of taking a hit and just talking about it and not much more I think is on the Mullah's foot.
