The opening paragraph of this news story is rather chilling:
BAGHDAD - Iraq's government, seeking protection against foreign threats and internal coups, will offer the U.S. a long-term troop presence in Iraq in return for U.S. security guarantees as part of a strategic partnership, two Iraqi officials said Monday.
So it's not a conspiracy theory, it's now front page news, that the current people running Iraq would not be able to maintain their rule without US troops. When other countries do this, it's usually called a "puppet government."
And isn't it a rather odd "deal"? "Okay, tell you what. If you agree to provide us with security, we agree to let your troops stay here and provide security."
It's almost as if the US government likes to have its troops stationed around the world...
