Greenspan: War Was About Oil

Critics of the Iraq war have always said the war was about oil, but they have been dismissed.
However Alan Greenspan, the former Federal Reserve chairman, has now shaken the White House by declaring that the prime motive for the war in Iraq was oil after all.
In his long-awaited memoir, Greenspan a well respected Republican, said that Saddam Hussein posed a threat to the security of oil supplies in the Middle East. “I am saddened that it is politically inconvenient to acknowledge what everyone knows: the Iraq war is largely about oil,” he says.
He said that the removal of Saddam Hussein had been “essential” to secure world oil supplies, a point he emphasized to the White House in private conversations before the 2003 invasion of Iraq.
