Another piece of evidence consists of documents which President Bush referenced as in his 2003 State of the Union Speech. According to Bush, these documents proved that Iraq was buying tons of uranium oxide, called "Yellow Cake" from Niger.

Since Israel had bombed Iraq's nuclear power plant years before, it was claimed that the only reason Saddam would have for buying uranium oxide was to build bombs.
This hoax fell apart fast when it was pointed out that Iraq has a great deal of uranium ore inside their own borders and no need to import any from Niger or anywhere else. The I.A.E.A. then blew the cover off the fraud by announcing that the documents Bush had used were not only forgeries, but too obvious to believe that anyone in the Bush administration did not know they were forgeries! The forged documents were reported as being "discovered" in Italy by SISMI, the Italian Security Service. Shortly before the "discovery" the head of SISMI had been paid a visit by Michael Ledeen, Manucher Ghorbanifar, and two officials from OSP, one of whom was Larry Franklin, the Israeli spy operating inside the OSP.
