There has been a lot of worthless chatter about what President Barack Obama should say about Iran’s incipient “Green Revolution.” Sorry, but Iranian reformers don’t need our praise. They need the one thing we could do, without firing a shot, that would truly weaken the Iranian theocrats and force them to unshackle their people. What’s that? End our addiction to the oil that funds Iran’s Islamic dictatorship. Launching a real Green Revolution in America would be the best way to support the “Green Revolution” in Iran.

Oil is the magic potion that enables Iran’s turbaned shahs  “Shah Khamenei” and “Shah Ahmadinejad”  to snub their noses at the world and at many of their own people as well. President Mahmoud Ahmadinejad behaves like someone who was born on third base and thinks he hit a triple. By coincidence, he’s been president of Iran during a period of record high oil prices. So, although he presides over an economy that makes nothing the world wants, he can lecture us about how the West is in decline and the Holocaust was a “myth.” Trust me, at $25 a barrel, he won’t be declaring that the Holocaust was a myth anymore.

The Obama team wants to pursue talks with Iran over its nuclear program, no matter who wins there. Fine. But the issue is not talk or no talk. The issue is leverage or no leverage. I love talking to people  especially in the Middle East  on one condition: that we have the leverage. As long as oil prices are high, Iran will have too much leverage and will be able to resist concessions on its nuclear program. With oil at $70 a barrel, our economic sanctions on Iran are an annoyance; at $25, they really hurt.

“People do not change when you tell them they should; they change when they tell themselves they must,” observed Michael Mandelbaum, the Johns Hopkins University foreign policy specialist. And nothing would tell Iran’s leaders that they must change more than collapsing oil prices.
