Actually I guess you could say there's a fourth overriding one which is the connection between the first two. . . . The third one by itself, as I think I said earlier, is a reason to help the Iraqis but it's not a reason to put American kids' lives at risk, certainly not on the scale we did it. That second issue about links to terrorism is the one about which there's the most disagreement within the bureaucracy, even though I think everyone agrees that we killed 100 or so of an al Qaeda group in northern Iraq in this recent go-around, that we've arrested that al Qaeda guy in Baghdad who was connected to this guy Zarqawi whom Powell spoke about in his U.N. presentation.
In short, Wolfowitz made the perfectly sensible observation that more than just WMD was of concern, but that among several serious reasons for war, WMD was the issue about which there was widest domestic (and international) agreement.
