Under escalating pressure from U.S. sanctions, Iran’s leaders face an existential crisis. As a result, they are increasingly likely to strike out against the U.S. in response.

The latest U.S. action against Iran came on Monday when Secretary of State Mike Pompeo ended waivers that allow foreign nations to purchase Iranian oil without U.S. sanction reprisals. Pompeo, however, also pledged that Saudi Arabia and the United Arab Emirates will increase their oil production to maintain price stability. It’s the correct course of action.
