Sometimes the whole country wants to forget.
Tuesday marks the 10th anniversary of the start of the war in Iraq. The last U.S. troops didn't leave that country until the end of 2011.
But Iraq, which dominated much of the nation's political discourse over the past decade, already seems largely forgotten.
"The Iraq War casts a shadow, but not a very large one," says Richard Kohn, a military historian at the University of North Carolina, Chapel Hill.
