It seems that when the "cold war" ended, the U.S. gov't. found time/desire to go searching for a new enemy for conquest (the islamic third world replaces the ru SSKI communists).
It also seems that the trend is to PRIVATIZE all manner of "security", even the MILITARY operations with mercenary forces such as Blackwater "security" in Iraq and all approximately 160,000 military contractors in Iraq (this is not a "war" of soveriegnties, what is it really?). Even the soldiers HATE Blackwater.
