Missing Weapons No Biggie

White House Downplays Missing Arms Report
  Since the war, U.S. teams took over the weapons search. Former chief arms hunter Charles Duelfer and his Iraq Survey Group found no weapons of mass destruction in the country, discrediting President Bush's stated rationale for invading Iraq.
  McClellan referred to findings by Duelfer, saying that 'any looting was the work of uncoordinated elements rather than directed at an effort to try to export equipment to a country that might obtain or have a weapons of mass destruction program.'
  He also noted that Duelfer had concluded that, since the looted materials are easily obtained elsewhere, 'other governments are not likely to look to Iraq to buy used versions of it.'

So, any weapons-related materials or equipment that have gone missing since the US-led invasion are not a concern, even though any weapons-realted materials or equipment found by the "coalition" upon invasion were immediately hyped as confirmation of a grave threat. Is this merely a logical inconsistency, or is McClellan confirming there was never actually any threat-related rationale for invading Iraq?
