Excepts from Sec. of State Colin Powell's UN speech Feb 5th, 2003:

Sources
My colleagues, every statement I make today is backed up by sources, solid sources. These are not assertions. What we're giving you are facts and conclusions based on solid intelligence. I will cite some examples, and these are from human sources.
****
Ladies and gentlemen, these are not assertions. These are facts, corroborated by many sources, some of them sources of the intelligence services of other countries.

Nuclear Weapons
Let me turn now to nuclear weapons. We have no indication that Saddam Hussein has ever abandoned his nuclear weapons program. On the contrary, we have more than a decade of proof that he remains determined to acquire nuclear weapons

The Al Quida Connection
Going back to the early and mid-1990s, when bin Laden was based in Sudan, an Al Qaida source tells us that Saddam and bin Laden reached an understanding that Al Qaida would no longer support activities against Baghdad. Early Al Qaida ties were forged by secret, high-level intelligence service contacts with Al Qaida, secret Iraqi intelligence high-level contacts with Al Qaida.

We know members of both organizations met repeatedly and have met at least eight times at very senior levels since the early 1990s. In 1996, a foreign security service tells us, that bin Laden met with a senior Iraqi intelligence official in Khartoum, and later met the director of the Iraqi intelligence service.

Saddam became more interested as he saw Al Qaida's appalling attacks. A detained Al Qaida member tells us that Saddam was more willing to assist Al Qaida after the 1998 bombings of our embassies in Kenya and Tanzania. Saddam was also impressed by Al Qaida's attacks on the USS Cole in Yemen in October 2000.

Iraqis continued to visit bin Laden in his new home in Afghanistan. A senior defector, one of Saddam's former intelligence chiefs in Europe, says Saddam sent his agents to Afghanistan sometime in the mid-1990s to provide training to Al Qaida members on document forgery.

From the late 1990s until 2001, the Iraqi embassy in Pakistan played the role of liaison to the Al Qaida organization.

Some believe, some claim these contacts do not amount to much. They say Saddam Hussein's secular tyranny and Al Qaida's religious tyranny do not mix. I am not comforted by this thought. Ambition and hatred are enough to bring Iraq and Al Qaida together, enough so Al Qaida could learn how to build more sophisticated bombs and learn how to forge documents, and enough so that Al Qaida could turn to Iraq for help in acquiring expertise on weapons of mass destruction.

And the record of Saddam Hussein's cooperation with other Islamist terrorist organizations is clear. Hamas, for example, opened an office in Baghdad in 1999, and Iraq has hosted conferences attended by Palestine Islamic Jihad. These groups are at the forefront of sponsoring suicide attacks against Israel.

Al Qaida continues to have a deep interest in acquiring weapons of mass destruction. As with the story of Zarqawi and his network, I can trace the story of a senior terrorist operative telling how Iraq provided training in these weapons to Al Qaida.

The Threat to America
The United States will not and cannot run that risk to the American people. Leaving Saddam Hussein in possession of weapons of mass destruction for a few more months or years is not an option, not in a post-September 11th world.

Excerpt from 2003 State of the Union

The Al Qaida Connection
With nuclear arms or a full arsenal of chemical and biological weapons, Saddam Hussein could resume his ambitions of conquest in the Middle East and create deadly havoc in that region. And this Congress and the America people must recognize another threat. Evidence from intelligence sources, secret communications, and statements by people now in custody reveal that Saddam Hussein aids and protects terrorists, including members of al Qaeda. Secretly, and without fingerprints, he could provide one of his hidden weapons to terrorists, or help them develop their own.

Before September the 11th, many in the world believed that Saddam Hussein could be contained. But chemical agents, lethal viruses and shadowy terrorist networks are not easily contained. Imagine those 19 hijackers with other weapons and other plans -- this time armed by Saddam Hussein. It would take one vial, one canister, one crate slipped into this country to bring a day of horror like none we have ever known. We will do everything in our power to make sure that that day never comes.

Some have said we must not act until the threat is imminent. Since when have terrorists and tyrants announced their intentions, politely putting us on notice before they strike? If this threat is permitted to fully and suddenly emerge, all actions, all words, and all recriminations would come too late. Trusting in the sanity and restraint of Saddam Hussein is not a strategy, and it is not an option.
