Big Oil returning to Iraq?

I have to confess I wondered how long it might be before the big oil boys started to try to get back into Iraq. This from the Independent reports that they are already negotiating their return with the Iraqi government.

So overthrowing Saddam was, hmmmmmm, solely about weapons of mass destruction? Methinks likely not.

Addendum:
Looks like I'm not the only one pondering that last statement - see this very enlightening article from ukwatch.net, which suggests that peak oil concerns were the primary reason for the war in Iraq.
