Ten years ago this month, the United States invaded Iraq. While combat
forces were withdrawn at the end of 2011, there is still a significant U.S.
presence in Iraq, and many people in both countries will never recover fully
from the effects of the fighting. It is worth remembering the invasion and
considering the costs if we are to avoid the fate warned of by George
Santayana: "Those who do not learn from history are doomed to repeat it."
