The stated objective of the harsh sanctions is to change the Regime’s “behavior.” However, there’s no defined way to measure the “behavior” change short of a Regime change. In other words, how would Pompeo measure the Regime’s behavior change in Karbala or Najaf where many of the Regime’s heads come from?

So if the real objective is to change the Regime, then the focus should be on first, building an alternative, and second, empowering the Iranian people to fight and topple the Regime. Harsh sanctions only weakens the Iranian masses and forces many who should stay and fight to leave Iran, as it is happening now.

I don't see this as a problem at all. The Islamic Republic's allies will step in immediately and start buying Iranian oil, and that will make up the lost revenue. And by IR's "allies" I mean the Lebanese Hezbollah, the Palestinian Islamic Jihad, and the Polisario Front. Those are the only allies the IR has left. I'm sure Hassan Nasrollah will need the gas to get from his hiding hole in South Lebanon to the IR's embassy to collect his weekly paychecks, and get his weekly sigheh-s, who are imported fresh on a weekly basis from Tehran. That, in and of itself, should be about 20 gallons of gas per week!
