Yeah, door #3 is we just sit back and let the blockade do it's job / work. In short order, Iran's oil infrastructure will crumble and the crushing reality of actual economic austerity will begin to set in and will take a toll on the people and the regime of Iran. Long term, this will destabilize and delegitimize them. That will increase the likelihood of regime change, and in all honestly, the best kind of regime change since it will happen organically. What we (Trump) likely doesn't have is the balls to wait it out or sell it to the American people in a clean way. I think he tried the other day, but the message fell flat. What I think probably happens is we split the difference. We'll commit enough men and material to opening the straight and denying Iran their ability to project power, whilst simultaneously disallowing Iranian shipments through. I was right about us starting the blockade - because it was obvious. I'm not as certain about this course of action. If I was in charge, that'd be my strategy though.
