The United States is Georgia’s closest ally. It maintained about 130 military advisers in Georgia, along with civilian advisers, contractors involved in all aspects of the Georgian government and people doing business in Georgia. It is inconceivable that the Americans were unaware of Georgia’s mobilization and intentions. It is also inconceivable that the Americans were unaware that the Russians had deployed substantial forces on the South Ossetian frontier. U.S. technical intelligence, from satellite imagery and signals intelligence to unmanned aerial vehicles, could not miss the fact that thousands of Russian troops were moving to forward positions. The Russians clearly knew the Georgians were ready to move. How could the United States not be aware of the Russians? Indeed, given the posture of Russian troops, how could intelligence analysts have missed the possibility that the Russians had laid a trap, hoping for a Georgian invasion to justify its own counterattack?
