CNSNews.com) – A majority of all combat-related U.S. casualties in the nine-year-long war in Afghanistan have occurred since President Barack Obama was inaugurated a little more than 17 months ago.

Between Jan. 20, 2009 and July 2, 2010, according to CNSNews.com's database of Afghanistan war casualties, U.S. military personnel suffered 452 combat-related deaths in Afghanistan. That amounts to more than half of the total of 900 combat-related fatalities suffered by U.S. forces in Afghanistan during the entire nine years of the war.
