The United States has accelerated preparations that officials and analysts say could support a potential large-scale military strike on Iran, marked by a critical diplomatic drawdown and a historic massing of regional forces. On February 27, the U.S. State Department officially updated its travel advisory, authorizing the departure of non-emergency government personnel and their families from Mission Israel. In an overnight email, Ambassador Mike Huckabee urged staff wishing to leave to “do so TODAY,” signaling an urgent window for departure before commercial options could become limited if regional security degrades further.
