Iran Warns "Fully Prepared for War" Amid U.S. Threat and Unrest

Iran says it is "fully prepared for war" if the United States intervenes, as nationwide protests enter a third week. The warning follows a U.S. threat of military action. U.S. President Donald Trump stated that Iran has since proposed negotiations. Tehran confirmed it is ready for talks, but only if they are based on "mutual respect." The protests began over economic issues. A government crackdown has reportedly led to hundreds of deaths. In a related development, the son of Iran's ousted Shah has said he is "prepared to return" to the country. Analysts consider such a return highly unlikely given the current political situation. The crisis continues with no clear resolution in sight.
