I'm very much afraid you are exactly right.
I just watched a segment on O'Reilly talking about a Trojan horse operation run against us in Iraq that resulted in the kidnapping and murder of US troops. It involved 4 or 5 SUVs (later abandoned!), US weapons, US and Iraqi uniforms, fake Iraqi (maybe also US - not sure about that) ID. Obviously it took a lot of money, planning, preparation, training, and resources to put that together not to mention a secure location. Iran is the only power in the region that has the wherewithal to pull that off. Baker and the majority of the senate and congress want the US to talk to Iran rather than bomb them. The world is upside down.
Isn't that the Karbala operation?
