"Didn't the Iraq report say we need Irans help???" - No it DID NOT.
Obviously you did not read the Report and are content to take the word of those who twist words/meanings, i.e. Rush/Sean/ Michael Savage, etc. to suit their agenda.
This is what The Iraq Study Report DID say...
"Dealing with Iran and Syria is controversial. Nevertheless, it is our view that in diplomacy a nation can and should engage its adversaries and enemies to try to resolve conflicts and differences consistent with its own interests."
