Cheney says it's too soon to tell on Iraqi arms

"I am a long way at this stage from concluding that somehow there was some fundamental flaw in our intelligence," Cheney said

Cheney suggested that biological weapons are hard to find because they could be produced on short notice. "The stuff is perishable and doesn't last very long anyway," he said. But, he added, intelligence is "never perfect. It's rarely 100% complete."

The Iraq invasion is helping the administration deal with other foreign policy hot spots. "If you do, in fact, use military force, as we did in Iraq, it makes your diplomacy more effective going forward, dealing with other problems."
