WHAT THEY AREN'T TELLING US: I think it's important to realize that even as trickles of information are now coming out of Iraq that implicate France (France, France, France), Russia (Russia), Germany, George Galloway, and aliens as aiding and abetting Saddam's thugocracy, there are likely to be pieces of juicy blackmail material that the US government is going to secretly hold on to for now. We're going to air enough filth to put our enemies in their places, and we're going to let them know through channels that there's plenty more where that came from and if they don't want it relvealed then they had better keep their mouths shut and stay out of our way.
That's how the world works, and the fact that our enemies don't know exactly what we've found gives us that much more power over them. I expect that we've got the goods on the various surrounding Arab countries as well, but it will be harder to blackmail the governments of nations that don't have a reasonably free press. Obviously the US government would never release incriminating evidence itself; rather, it would be leaked through media sources as having been "just discovered" so as it give it more credibility among anti-American populations.
