The Yemen Deal

Both the United States and the Houthis needed a deal for different reasons. But the deal won’t create any sort of lasting or sustainable framework for peace in the Red Sea.

Betting Big in Yemen

For the Houthis, this is an existential fight. But the United States has a harder path to success.

Yemen’s Weakest Link: The Presidential Leadership Council

To eliminate the Houthis' capabilities, the United States will need the support of Yemen's Presidential Leadership Council, a body plagued by infighting and incompetence.

The Coming War in Yemen

Trump’s executive order redesignating the Houthis a foreign terrorist organization threatens direct military action against the Houthis, raising the possibility that the United States could get sucked into another long-term conflict in the Middle East.

Great Power Competition in the Red Sea

For the United States, the Houthi threat in the Red Sea should be treated as part of strategic competition instead of merely a local or regional challenge.
