The Iraq war was about oil and nothing more.
Nope. You're such a simple sheep. Bush had already started implementing US oil independence before the invasion.

The war was about the terrorists that Saddam WAS harboring and the WMD he DID have. Give me evidence of one ml of Iraqi oil that's been comandeered by the US since the invasion.
The current situation was created by the Arab Spring (completely independent of Bush invading Iraq) and Obama (Arab Spring supported by Obama in Libya) and Obama's weakness in the region (ie pulling US troops out of Iraq too early).
