That should've been the first serious flag for everyone. How do you start a war on false assumptions, create a torture base, keep the torture base, and then you just say "we need to move on" (from the accusations, presumably)?
What's US' credibility in the world when you just do that? It's almost like Germany not admitting the holocaust happen. US may have not killed millions, but it did kill over 100,000 Iraquees.
