The U.S. hit a sad milestone over the weekend when the 2,000th American service member was killed in the 11-year conflict in Afghanistan.

While international participation in Afghanistan is drawing down, tens of thousands of our soldiers remain in harm’s way helping to train the Afghan government and police forces to independently maintain national security once the remaining foreign troops depart in about two years.

Many of the U.S. deaths in recent months are the result of sneak attacks by our supposed allies, Afghan soldiers and police officers who our troops are training.
