http://www.aljazeera.com/cgi-bin/news_service/middle_east_full_story.asp?service_id=9665The Bush administration had numerous chances to arrest the Jordanian militant Ahmad al-Khalayleh, known as Abu Musab al-Zarqawi, if he does really exist, since February 2003 speech of the former Secretary of State Colin Powell at United Nations Security Council, a great portion of which was given to the “terrorist camp in Khurmal”, in the pre-invasion Kurdish enclave.
It was at that camp that Zarqawi supposedly fled Afghanistan, and Kurds were receiving intensive training to produce the poison ricin and cyanide.
At that time, the Khurmal camp and the area surrounding it were out of Saddam Hussein's control, but Powell fabricated evidence, largely discredited by the intelligence community, to show that Zarqawi does have ties to the Iraqi regime.
Al Zarqawi's "headquarters" were bombed to the ground by U.S. forces that year, and some news sources claimed that he had been killed, but his name keeps recurring whenever the U.S. needs.
Almost every attack that takes place in Iraq is attributed to Al Zarqawi, and his so-called Al Qaeda military wing in Iraq. No car or roadside bomb attacks occur unless they're attributed to him by the U.S.
