Ed Morrissey at Captain's Quarters is very skeptical that those Iraqi mobile laboratories were being used to make hydrogen gas for weather balloons. Recently translated documents suggest a much more sinister purpose, but since that purpose is pretty much what the administration said before the war, the MSM has pretty much ignored the documents and their implications.
You can read Morrissey's take here.
Meanwhile, it should be noted that every captured document that has been translated has so far been consonant with, or actually supports, the White House's justification for going to war (WMD and Saddam's association with terrorists), and none of them have, as yet, been incompatible with it. We're waiting for the "Bush lied" crowd to at least acknowledge that he may have had good reason for believing what he was telling the American people in early 2003.
