A lot of poor commentary has framed the Iraq war as a conflict of "choice" rather than of "necessity." In fact, President George W. Bush chose to remove Saddam Hussein from power because he concluded that doing so was necessary.
President Bush inherited a worrisome Iraq problem from Bill Clinton and from his own father. Saddam had systematically undermined the measures the U.N. Security Council put in place after the Gulf War to contain his regime. In the first months of the Bush presidency, officials debated what to do next.
As a participant in the confidential, top-level administration meetings about Iraq, it was clear to me at the time that, had there been a realistic alternative to war to counter the threat from Saddam, Mr. Bush would have chosen it.

The Iraq policy debate remained unresolved when the September 11 attacks occurred. Like all major national security issues, Iraq policy was re-examined in light of our post-9/11 sense of vulnerability and the heightened worries about terrorism and, especially, about the danger that terrorists might obtain WMD from a nation state.
When the president ultimately decided that the Iraqi regime must be ousted by force, he was influenced by five key factors:
1) Saddam was a threat to U.S. interests before 9/11. The Iraqi dictator had started wars against Iran and Kuwait, and had fired missiles at Saudi Arabia and Israel. Unrepentant about the rape of Kuwait, he remained intensely hostile to the U.S. He provided training, funds, safe haven and political support to various types of terrorists. He had developed WMD and used chemical weapons fatally against Iran and Iraqi Kurds. Iraq's official press issued statements praising the 9/11 attacks on the U.S.
2) The threat of renewed aggression by Saddam was more troubling and urgent after 9/11. Though Saddam's regime was not implicated in the 9/11 operation, it was an important state supporter of terrorism. And President Bush's strategy was not simply retaliation against the group responsible for 9/11. Rather it was to prevent the next major attack. This focused U.S. officials not just on al Qaeda, but on all the terrorist groups and state supporters of terrorism who might be inspired by 9/11 – especially on those with the potential to use weapons of mass destruction.
3) To contain the threat from Saddam, all reasonable means short of war had been tried unsuccessfully for a dozen years. The U.S. did not rush to war. Working mainly through the U.N., we tried a series of measures to contain the Iraqi threat: formal diplomatic censure, weapons inspections, economic sanctions, no-fly zones, no-drive zones and limited military strikes. A defiant Saddam, however, dismantled the containment strategy and the U.N. Security Council had no stomach to sustain its own resolutions, let alone compel Saddam's compliance.
4) While there were large risks involved in a war, the risks of leaving Saddam in power were even larger. The U.S. and British pilots patrolling the no-fly zones were routinely under enemy fire, and a larger confrontation – over Kuwait again or some other issue – appeared virtually certain to arise once Saddam succeeded in getting out from under the U.N.'s crumbling economic sanctions.
Mr. Bush decided it was unacceptable to wait while Saddam advanced his biological weapons program or possibly developed a nuclear weapon. The CIA was mistaken, we all now know, in its assessment that we would find chemical and biological weapons stockpiles in Iraq. But after the fall of the regime, intelligence officials did find chemical and biological weapons programs structured so that Iraq could produce stockpiles in three to five weeks. They also found that Saddam was intent on having a nuclear weapon. The CIA was wrong in saying just before the war that his nuclear program was active; but Iraq appears to have been in a position to make a nuclear weapon in less than a year if it purchased fissile material from a supplier such as North Korea.
5) America after 9/11 had a lower tolerance for such dangers. It was reasonable – one might say obligatory – for the president to worry about a renewed confrontation with Saddam. Like many others, he feared Saddam might then use weapons of mass destruction again, perhaps deployed against us through a proxy such as one of the many terrorist groups Iraq supported.
Thoughtful, patriotic Americans differed then and now on whether the risk of leaving Saddam in power outweighed the risk of war. But Mr. Bush concluded that it did, and that war therefore was necessary. In Congress, many Democrats as well as Republicans supported that conclusion. Debates will continue over whether the president should have balanced the risks differently. But characterizing the Iraq war as "a war of choice" sheds no light on the issue.
