The front in the war on terror is Iraq.
Saddam had WMD. Duh.
Saddam’s regime had dealings with Niger for yellowcake (or goats). And he had dealings with OTHER countries for yellowcake. See deets on that here.
Money Quote from Butler Report :
499. We conclude that, on the basis of the intelligence assessments at the time, covering both Niger and the Democratic Republic of Congo, the statements on Iraqi attempts to buy uranium from Africa in the Government’s dossier, and by the Prime Minister in the House of Commons, were well-founded. By extension, we conclude also that the statement in President Bush’s State of the Union Address of 28 January 2003 that:

The British Government has learned that Saddam Hussein recently sought significant quantities of uranium from Africawas well-founded.
Saddam’s regime had dealings with, gave financial help to, and trained terrorists, including Al Qaeda. See previous posts here and here and check out Tom Joscelyn’s blog here.

Why is Rummy a target? Read here and here. Rummy says late today that he won’t quit.
For your reading pleasure all you Joe Wilson fans:

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.
