Lol. I am going to regret this, I know it!
What people don't seem to get about Trump is that he is not after fighting with people by way of war. He believes and has always believed that economic pressure and promise of reward is the way to go. He has not gotten us into more conflicts as the last president did. He has not expanded our involvement in things as the last president did except to bomb the crap out of ISIS in Syria. This appears to have been an effective strategy. Trump is far less likely to resort to force than many of our presidents of the past, including the last one.
Iran is run by Islamist ideologues of the worst type. Even other countries of the same Muslim sect do not agree with what Iran believes. They are 12ers, but unlike others who believe as they do, they believe that Iran has been chosen to usher in the Mahdi. What does the Mahdi need to appear? Chaos, war, famine, death. If you look at some of the videos that have come out of Iran, they show the world on fire. Not only do they believe they have this special place in prophecy, but they believe the Mahdi is here and only needs the right conditions to appear. That adds a little urgency to the whole chaos thing.
In 2009 our government was approached by Iranians who wanted to overthrow the nutters running the country. Not only did the Obama admin fail to help, they would not even verbally support them. It might have been the last best chance to do something, but we failed. Obama had a thing for Islamists. He was better at gun running to ISIS that supporting reform.
Do most of the people of Iran want war? I doubt it. If their government does something stupid they are going to get war. Pretty sure in any war most of the population doesn't want it coming to them, but so it goes.
Brits should know that better than most.
I have said before and will say again; if there ever was a country that would use nukes when they got them, Iran is that country.
BTW, did you guys know that there are sunset clauses in the Iran deal with no plan for dealing with what they do after those clauses kick in? They kick in in 2025, 28, and 30, and will allow Iran to carry on as they were if we are working on the assumption that they are now complying. For a country that plays the long game, this was an easy get for them. Billions of dollars and lifting sanctions and they just have to be careful for a few years.
