The Houthis in Yemen, the Islamist rebel group that has shot missiles and drones at Israel and is now intensifying attacks on key shipping lanes in the Red Sea, have progressed from being "a nuisance and a headache to a major strategic threat to Israel," according to Dr. Yoel Guzansky, a former member of Israel's National Security Council and a senior researcher at the Institute for National Security Studies.

Their escalating attacks on international shipping over the course of the Israel-Hamas conflict have raised the stakes of Israel's conflict with its neighbors into a global concern. On Monday, the U.S. announced the formation of a coalition of ten nations to take action against the Houthi aggression against cargo ships which threatens global trade.

On the Haaretz Weekly podcast, Guzansky, and Haaretz National Security editor Avi Scharf, sit down with host Allison Kaplan Sommer to discuss who the Houthis are and how Israel - and the world - should respond to them.
