Tuesday was one of the more bizarre days in U.S. diplomatic history. It began with President Donald Trump warning that, should Iran not reopen the Strait of Hormuz, “a whole civilization will die tonight.” It ended with Trump proclaiming a two-week ceasefire and opening negotiations with Iran based on Tehran’s “10 point proposal.” There is rampant confusion about what those 10 points are, but the version released by Tehran calls for, among other things, Iranian control of the Strait of Hormuz, U.S. military withdrawal from the region and acceptance of Iran’s right to pursue nuclear enrichment — all conditions that should be utterly unacceptable to any U.S. administration.
