The US has warned the Persian Gulf states of a possible military campaign against Iran after the November 3 congressional elections. The operation could be short but intense, the Wall Street Journal reports, and US officials noted. No final decision has been made yet. According to the report, the US is already moving Patriot air defense systems to the area from Texas to strengthen missile defense. American forces crash munitions, bombers and fighter planes are called for attacks. A second airline strike group could join the flotilla of about 20 ships next month.
