To the extent that this ends in military action, it's going to be the rest of the world protecting the Iranian toll regime from USA piracy. Even Trump won't pull that trigger. Watch for the TACO.
I don't see that happening... Also if they want to escort tankers, they can escort tankers from US-allied countries, and I assume US would also help.
Overall, I legit do not see a way where countries would pick to fight against US instead of Iran if we ever get there. But maybe, I am wrong, so who knows :)
No, but I believe China and Europe believe that they can stare down Trump and force a TACO more than they believe in their ability to successfully navigate the ridiculous shitstorm in the gulf.
I repeat for like the ninth time: It is the USA, and not Iran, that is actually preventing commerce in the gulf as a matter of national policy. Iran just wants to get paid, basically. Trump wants... what, exactly? And that's the problem. The rest of the world needs a solution and not bluster. Iran offers one, Trump just yells a lot.
