The United States military finally declared an end to their mission in Iraq, but vowing to still keep a close eye on any potential terrorist threats.

Over the course of nine years the war cost $800 billion, over 4,000 troops and countless Iraqi's were killed, but Defense Secretary Leon Panetta says it was purposeful.

"To be sure, the cost was high — in blood and treasure for the United States and also for the Iraqi people. But those lives have not been lost in vain."

President Obama promised he would bring the troops home in his 2008 campaign, which he followed through with. Now, thousands of families will be getting the Christmas present that no money could buy.
