DemocracyNow! on 2/27/07? He was interviewed about his new book and commented on the luxury of bases in Japan. I mention this because it underscores the points you are making about how having troops live in luxury isolates them from the local population and leads them to feel superior - making abuses far more likely.
DemocracyNow! interview with Chalmers Johnson...
In the southernmost prefecture of Japan, Okinawa, site of the Battle of Okinawa in 1945, there’s a small island, smaller than Kawaii in the Hawaiian islands, with 1,300,000 Okinawans. There's thirty-seven American military bases there. The revolt against them has been endemic for fifty years. The governor is always saying to the local military commander, “You're living on the side of a volcano that could explode at any time.” It has exploded in the past. What this means is just an endless, nonstop series of sexually violent crimes, drunken brawls, hit-and-run accidents, environmental pollution, noise pollution, helicopters falling out of the air from Futenma Marine Corps Air Base and falling onto the campus of Okinawa International University. One thing after another. Back in 1995, we had one of the most serious incidents, when two Marines and a sailor abducted, beat and raped a twelve-year-old girl. This led to the largest demonstrations against the United States since we signed the security treaty with Japan decades ago. It's this kind of thing.
I first went to Okinawa in 1996. I was invited by then-Governor Ota in the wake of the rape incident. I’ve devoted my life to the study of Japan, but like many Japanese, many Japanese specialists, I had never been in Okinawa. I was shocked by what I saw. It was the British Raj. It was like Soviet troops living in East Germany, more comfortable than they would be back at, say, Oceanside, California, next door to Camp Pendleton. And it was a scandal in every sense. My first reaction -- I’ve not made a secret of it -- that I was, before the collapse of the Soviet Union, certainly a Cold Warrior. My first explanation was that this is simply off the beaten track, that people don't come down here and report it. As I began to study the network of bases around the world and the incidents that have gone with them and the military coups that have brought about regime change and governments that we approve of, I began to realize that Okinawa was not unusual; it was, unfortunately, typical.
These bases, as I say, are spread everywhere. The most recent manifestation of the American military empire is the decision by the Pentagon now, with presidential approval, of course, to create another regional command in Africa. This may either be at the base that we have in Djibouti at the Horn of Africa. It may well be in the Gulf of Guinea, where we are prospecting for oil, and the Navy would very much like to put ourselves there. It is not at all clear that we should have any form of American military presence in Africa, but we're going to have an enlarged one.
