Use Iraqi military to seize the oilfields, easy with US air cover.
Then there will be no money for Iran to pay Pakis.
The Iraqi military is Shiite but maybe that would work. Even if all Iranian oil is shut off the Iranians must have some gold they could sell Pakistan or North Korea for a nuke to clandestinely detonate in Tel Aviv.
Good point except it requires landing troops in southern Iran (Khuzestan) and we are war-shy these days. Plus some nuke sites would pollute the oil fields anyway.
