Trump is finally doing the obvious thing. Shut off Iran’s oil exports.
What if China decides to force the strait? Trump will just offer to either sell them US oil, or double the tariffs *again*. And if that doesn’t do the trick, just blow up the loading pumps.
If Iran can’t ship oil, and every other gulf country can, this changes the situation completely. Can they start shooting again? Sure. But closing off their oil exports puts his hand around their throats.
Take Kharg intact. Blowing up Kharg is like cutting off a bulls balls and seizing Kharg is like tying a noose around the bulls balls.
