Sorry that you must take valuable time helping folks in Iraq to answer die-hard skeptics, but you seem to be doing a fine job a that, too.
To reinforce what you are saying...
First, I don't see how anyone can realistically conclude anything about the Bhutto assassination with so little evidence at this point.
Second, it seems that saying AQI created in Iraq is not from Bin Laden's Al Qaeda is login akin to Intelligent Design, which ironic, coming from the people promoting the disconnection.
Third, to say that AQI is not a threat to USA is so irrelevant, since by definition their purpose at this time is to fight in Iraq, and you cannot say for sure they do not intend no harm to us in the future, as their AQ moniker Jihad goals state.
My questions to you in the Assessment are:
1. Do you think the Iraqis are aware that the Americans may pull out relatively quiclky based on a 2008 election result if a Democrat like Obama or Edwards wins?
2. Are they getting enthusiastic about running their own country and resisting insurgents?
