but we'll never, ever, ever forget the terrible cost that we paid as a nation. many of you likely lost friends or colleagues in afghanistan and iraq. i know this is personal to you. especially as you head into memorial day weekend. we as a nation will always remember and pay tribute to knows we lost. after i announced my decision to end the war in afghanistan, the first thing i did was visit -- visit section 60 of arlington national cemetery. just walked through the head stones. seen all those stones. our son did not die in iraq. but he came back at an incredibly healthy young man and came back with a severe brain tumor, because his hooch was downwind from the burn pits.
