In the past few days, we've seen numbers of tankers going to China and Pakistan, no doubt other places too, passing through the straight of hormuz. This in my opinion is Iran selling off the gold before the bank is burglarized. They just need to turn off the supply to kharg when it's completely empty and make a switch to road-based tanking.
This doesn't eliminate the threat to their supply side, but it does make it harder for america to get at.
