In this July 11, 2011 picture, Xavier Montjoy plays a video game at his home in Columbus, Ohio. Montjoy was born hours before the terror attacks on Sept. 11, 2001. Like millions of children born in the past decade, Xavier has never known a world untouched by that day’s terror attacks. He’s played baseball and soccer and hates math like generations before him but is growing up in a new normal. In this world, Afghanistan has always been a place of war, and several of his relatives in the military have been deployed overseas. Border security was tightened, and there are travel restrictions that hamper family trips and force travelers to stand in security lines in socks or bare feet at the airport near his house on a tree-lined Columbus street.
