I think Pentagons goals and objectives for our region has remained the same for the past 2 decades I think every U.S. administration has had it's own strategy, tactics and time table to achieve those goals but I don't think their overall objectives change with the changing of U.S. presidents.
With BP, Italian steel companies and Maersk shipping leaving Iran and the end of the Airbus deal I just don't understand how you would think staying in the JCPOA would make any kind of sense!
As for Trump getting reelected, if Iran does nothing in response to Trump leaving the JCPOA and placing sanctions on Iran how exactly is that not a major political victory for him? He will easily fund his next campaign with Saudi and Israeli money which will allow him to outspend any potential rival and Israeli Mossad will assist him in social media and finding dirt or making up dirt against any potential rival!
And
MOST IMPORTANTLY if Iran does nothing and the pressures on Iran's economy mounts the Rohani administration will likely end up negotiating Iran's Missile Program away since they would have no other cards to give up at any potential negotiations whether it be with EU or the U.S.!
I'm sorry bro but staying in the JCPOA without substantial economic incentives and guarantees from China & EU is just absurd and with 3 major European companies leaving within a week it's clear the EU has not intention of going beyond political support for the JCPOA and that's just not enough!
Iran needs to leave the NPT and kick out IAEA inspectors and camera's and start installing IR-8's at a rate of at least 20 per day at two separate location 10 at Fordow and 10 at a new unknown location
And in terms of Military Iran needs to produce MIRV equipped version of the Khoramshar at a rate of 100 Per year + Increase production of Zolfaghar missile to at least 3 per day (With max output of 10-12 per day) + Production of 3-4 different types of land attack cruise missiles at a rate of 10 per day with max output of 50 per day and Iran needs to increase domestic weapons production to $20 Billion per year and focus on creating jobs & technology via the defense industry as a response to Trump
And if the U.S. attacks Iran's initial and immediate response should be mainly against U.S. puppets in U.S. puppet states + Oil facilities in Saudi Arabia and if you wanna prevent Trump from getting reelected then we need to drive Oil prices to $200 pb with Gasoline prices in the U.S. reaching $10 per gallon
As for any attack on Hezbullah what exactly is the U.S. going to bomb that the Israeli's didn't bomb in 2006? Hezbullah is a political origination and a movement that did pretty well in the last elections in Lebanon and bombs will just create more martyrs
As for Iranian forces getting attacked in Syria with no assistance coming from Russia that's something the Syrians have to take up with Russia and if the Syrian Military is ready to finish the job it's self all the better and as long as the political structure in Syria is intact I don't see Iran withdrawing from Syria as a defeat.
Iran's goal was to prevent Syira from falling in the hands of Daeesh and other terrorist not building military bases in Syria.
Iran and Turkey also want to prevent the U.S. & Israel from setting up an independent Kurdish state in Syria and I believe the Turks can handle themselves but Iran can also offer any help it can in that regard as well.
As for Iran's retaliation to those attacks if Iran was to respond on their timetable out of anger then the likelihood of success will be quite limited. Iran's response to attacks on Iranian forces outside Iran's soil has to be on Iran's own time table rather than on Israeli or U.S. time table.
