I agree with both cauliflower and boredfrom. Trump is so out of his league right now and he's just blustering forward. I think he really did think he could just scare the Iranians by parking his boats in their gulf and choking their economy. I'm sure Bolton and Pompeo were telling him the whole time that he should be prepared for military action but he wasn't listening and completely sure a shot wouldn't have to be fired. Well, Persians don't fuck around and the entire country has already unified against the US. It hasn't been this unified in decades. They're going to keep stockpiling enriched uranium, we're going to miss their deadline, they're going to go past the redline, and Trump will end up feeling more justified about bombing the shit out of the country. After that, all hell breaks loose, I guess.
We're not mobilized right now to go against a country like Iran at all and we'd be relying on Saudi, Israel, and if Egypt wants to get involved I don't know. That's why the DoD wanted to send 100,000 more troops over there but we only ended up sending like 6000 or something. Who knows what Russia does, too. A war would be extremely destructive to most of the region.
