Not hard at all.

Here's what he says:

"ÒBut conventional thinking in Washington lined up for war. The pundits judged the political winds to be blowing in the direction of the President. Despite - or perhaps because of how much experience they had in Washington, too many politicians feared looking weak and failed to ask hard questions. Too many took the President at his word instead of reading the intelligence for themselves. Congress gave the President the authority to go to war. Our only opportunity to stop the war was lost.
I made a different judgment. I thought our priority had to be finishing the fight in Afghanistan. I spoke out against what I called "a rash war' in Iraq. I worried about, Ôan occupation of undetermined length, with undetermined costs, and undetermined consequences.Õ The full accounting of those costs and consequences will only be known to history. But the picture is beginning to come into focus.Ó"

Here's a recap:

As a candidate for the United States Senate in 2002, Obama put his political career on the line to oppose going to war in Iraq, and warned of Òan occupation of undetermined length, with undetermined costs, and undetermined consequences.Ó Obama has been a consistent, principled and vocal opponent of the war in Iraq.

In 2003 and 2004, he spoke out against the war on the campaign trail;

In 2005, he called for a phased withdrawal of our troops;

In 2006, he called for a timetable to remove our troops, a political solution within Iraq, and aggressive diplomacy with all of IraqÕs neighbors;

In January 2007, he introduced legislation in the Senate to remove all of our combat troops from Iraq by March 2008.

In September 2007, he laid out a detailed plan for how he will end the war as president.
