This article explains the origins of the phony letter from the Niger dictator promising Iraq's dictator annual shipments of Uranium. Bush agents didn't create the letter; rather, some huckster trying to sell intelligence did.
But the article inexplicably assumes that falsifying this letter constitutes falsifying the contention that Hussein sought to obtain uranium from Niger, and that Niger's tyrannical government complied with this effort. It appears, though, that other evidence supports that contention, and no evidence clearly falsifies it. Believing that Hussein was complying with this portion of the 1991 cease fire agreements requires believing that as his sworn and feared enemy, "the Persians", sought a nuclear arsenal, he did not.
