Reply #51: It might help if you read General Clark's opening statement

[Spazito]

when he testified before the House in September of 2002, BEFORE the Iraq invasion:

Saddam has been pursuing nuclear weapons for over twenty years. According to all estimates made available he does not now have these weapons. The best public assessment is that if he were to acquire fissionable material he might field some type of weapon within two years. If he has to enrich the uranium ore itself, then a period of perhaps five years might be required. But what makes the situation relatively more dangerous today is that the UN weapons inspectors, who provided some assistance in impeding his development programs, have been absent from Iraq for over four years. And the sanctions regime, designed to restrict his access to weapons materials and the resources needed to procure them, has continuously eroded. At some point, it may become possible for Saddam to acquire the fissionable materials or uranium ore that he needs. And therefore, Iraq is not a problem that can be indefinitely postponed.

The critical issue facing the Unites States now is how to force action against Saddam Hussein and his weapons programs without detracting from our focus on Al Qaeda or efforts to deal with other immediate, mid and long-term security problems. In this regard, I would offer the following considerations:

- The United States diplomacy in the United Nations will be further strengthened if the Congress can adopt a resolution expressing US determination to act if the United Nations will not. The use of force must remain a US option under active consideration. The resolution need not at this point authorize the use of force, but simply agree on the intent to authorize the use of force, if other measures fail. The more focused the resolution on Iraq and the problem of weapons of mass destruction, the greater its utility in the United Nations. The more nearly unanimous the resolution, the greater its impact in the diplomatic efforts underway.

Force should be used as the last resort; after all diplomatic means have been exhausted, unless information indicates that further delay would present an immediate risk to the assembled forces and organizations. This action should not be categorized as "preemptive."

Even more interesting was the question and answer period that followed his opening statement. Unfortunately I have, as yet, been unable to find the transcript of that portion of his testimony, hopefully someone else might.
