The following is an excerpt from Chalmers Johnson’s new book, Dismantling the Empire: America’s Last Best Hope (Metropolitan Books, 2010).

However ambitious President Barack Obama’s domestic plans, one unacknowledged issue has the potential to destroy any reform efforts he might launch. Think of it as the 800-pound gorilla in the American living room: our longstanding reliance on imperialism and militarism in our relations with other countries and the vast, potentially ruinous global empire of bases that goes with it. The failure to begin to deal with our bloated military establishment and the profligate use of it in missions for which it is hopelessly inappropriate will, sooner rather than later, condemn the United States to a devastating trio of consequences: imperial overstretch, perpetual war, and insolvency, leading to a likely collapse similar to that of the former Soviet Union.

According to the 2008 official Pentagon inventory of our military bases around the world, our empire consists of 865 facilities in more than 40 countries and overseas U.S. territories. We deploy over 190,000 troops in 46 countries and territories. In just one such country, Japan, at the end of March 2008, we still had 99,295 people connected to U.S. military forces living and working there — 49,364 members of our armed services, 45,753 dependent family members, and 4,178 civilian employees. Some 13,975 of these were crowded into the small island of Okinawa, the largest concentration of foreign troops anywhere in Japan.
