Mohammad Tabaar argues that the attacks on Red Sea ships unintentionally advance the Houthis agenda by allowing it to claim that it is fighting imperialism, and the attacks help Iran by fortifying its political foothold in the Middle East. Washington should therefore cease the strikes. It should, instead, work to halt the war in Gaza.

Joseph S. Nye writes that evaluating ethics in international relations is difficult, and Kissinger's legacy is particularly complex. Over his long tenure in government, he had many great successes, including with China and the Soviet Union and the Middle East. Kissinger also had major failures, including in how the Vietnam War ended. But on net, his legacy is positive. In a world haunted by the specter of nuclear war, his decisions made the international order more stable and safer.
