Long term the answer is obviously no; however, that doesn't mean Iran could not prevail long enough to kill 20,000 US servicemen and women according to a 2002 Pentagon simulation: From GlobalResearch: "Even the Pentagons own war simulations have shown that a war in the Persian Gulf with Iran would spell (initial) disaster for the United States and its military. "One key example is the Millennium Challenge 2002 (MC02) war game in the Persian Gulf, which was conducted from July 24, 2002 to August 15, 2002 and took almost two years to prepare... "Millennium Challenge 2002 was held shortly after the Pentagon had decided that it would continue the momentum of the war in Afghanistan by targeting Iraq, Somalia, Sudan, Libya, Lebanon, Syria, and finishing off with the big prize of Iran in a broad military campaign to ensure U.S. primacy in the new millennium..." "The scenario in the 2002 war game started with the U.S., codenamed 'Blue,' giving Iran a one-day ultimatum to surrender in the year 2007. "The war games date of 2007 would chronologically correspond to U.S. plans to attack Iran after the Israeli attack on Lebanon in 2006, which was to extend, according to military plans, into a broader war against Syria. "The war against Lebanon, however, did not go as planned and the U.S. and Israel realized that if Hezbollah could challenge them in Lebanon then an expanded war with Syria and Iran would be a disaster. "In Millennium Challenge 2002s war scenario, Iran would react to U.S. aggression by launching a massive barrage of missiles that would overwhelm the U.S. and destroy sixteen U.S. naval vessels an aircraft carrier, ten cruisers, and five amphibious ships. "It is estimated that if this had happened in real war theatre context, more than 20,000 U.S. servicemen would have been killed in the first day following the attack. " The Geo-Politics of the Strait of Hormuz: Could the U.S. Navy be defeated by Iran in the Persian Gulf? 20,000 US servicemen and women dead in the first 24 hours followed by 200,000 -2,000,000 Muslim civilians killed in revenge within weeks (days?) Does anyone seriously believe scenarios like Millennium Challenge would be conceived if war was not a racket?
