Some quotes from resigned White House counter-terrorism adviser Rand Beers. He's now working with the John Kerry campaign.

The focus on Iraq has robbed domestic security of manpower, brainpower and money, he said. The Iraq war created fissures in the United States' counterterrorism alliances, he said, and could breed a new generation of al Qaeda recruits. Many of his government colleagues, he said, thought Iraq was an "ill-conceived and poorly executed strategy."

He thinks the war in Afghanistan was a job begun, then abandoned. Rather than destroying al Qaeda terrorists, the fighting only dispersed them. The flow of aid has been slow and the U.S. military presence is too small, he said. "Terrorists move around the country with ease. We don't even know what's going on. Osama bin Laden could be almost anywhere in Afghanistan," he said.
...
Within U.S. borders, homeland security is suffering from "policy constipation. Nothing gets done," Beers said. "Fixing an agency management problem doesn't make headlines or produce voter support. So if you're looking at things from a political perspective, it's easier to go to war."

This guy knows where the bodies are buried and he's beginning to talk.
