It’s game over.

That hinges on if the US Navy will board and/or fire on a 3rd party tanker that Iran is letting pass.

Shippers have insurance now and they don't care about the lives of their crews

With the price of gas, someone will order their ship to test it. If one goes thru, then a bunch will go at once.

Edit:

Hard to read around paywall, but article says trump is only "blockading" things going to/from an Iranian port...

Shit will just touch a port in another country first, not change cargo, and then sail right past...

Easy loophole, and still puts how bad this is, on if US ships will actually try to enforce anything
