Well my theory is that we killed or captured Osama long ago and WE are making the tapes urging terrorists to fight in Iraq where we are killing them at a 175 to 1 ratio. The media whining about a "quagmire" helps that strategery. The WMD's are (mostly) safely out of harm's way on some boat and Syria etc.
The Afgan campaign destroyed the training camps and madrasses, but it scattered many existing terrorists and freed them of their command structure making them more dangerous. Hence Iraq.
I thought of that as well, but that might be considered by too many to be something along the lines of, "SEE?! Bush IS the terrorist, and is responsible for all terror-related deaths after he captured OBL because he didn't tell anyone the truth. If he would have told the truth about OBL's capture or death, the terrorists would have given up."
Yes, the librats ARE that dim.
