The Red Sea crisis predates the Swords of Iron War, but became a specifically Israeli security threat after October 2023, with the start of a Houthi military-terrorist solidarity campaign with Hamas. The Houthis launched a blockade on Israeli-linked shipping, but also harmed Red Sea maritime traffic in general with attacks on ships, causing a 50% reduction in Suez Canal traffic within a few months and forcing the Israeli Port of Eilat to suffer serious losses. The cessation of Houthi attacks on US vessels in May 2025, following a ceasefire agreement with Washington, did not signal an end to the conflict but rather a shifting of the crosshairs to focus more on trying to blockade Israel from the south. Since the October 2025 Israel-Hamas ceasefire, the Houthis have held their fire against Israel. Reports suggest that the UAE, possibly with the quiet blessing of Saudi Arabia, and anti-Houthi forces within Yemen are building new strategic positions to deal with the ongoing radical Shiite threat from Saana.
