Two points:

First, the fake documents were irrelevant to this issue a long time ago.

From the Butler Report:

503. From our examination of the intelligence and other material on Iraqi attempts to buy uranium from Africa, we have concluded that:

a. It is accepted by all parties that Iraqi officials visited Niger in 1999.

b. The British Government had intelligence from several different sources indicating that this visit was for the purpose of acquiring uranium. Since uranium constitutes almost three-quarters of Niger’s exports, the intelligence was credible.

c. The evidence was not conclusive that Iraq actually purchased, as opposed to having sought, uranium and the British Government did not claim this.

d. The forged documents were not available to the British Government at the time its assessment was made, and so the fact of the forgery does not undermine it.

In point of fact, British intelligence stated several months ago, during the Great Sixteen Words flap, that their conclusions were not based on the false documents. I posted that here, and predictably it went in one ear and out the other. The media, predictably, also did not seem to notice this statement.

Second, I wouldn't trust the IAEA to be able to find its ass with both hands and a GPS unit. Its record over the past decade or so of identifying and/or neutralizing nuclear weapons programs in or sponsored by Iraq, North Korea, Iran, Libya, Pakistan and elsewhere is nothing to be proud of.
