Western Hatred by Our "Allies"

On October 25, Ned Parker of the Los Angeles Times wrote the article called "Two U.S Soldiers Slain by Gunman in Afghan Uniform". Here, the article discusses two more deaths caused by an Afghan police member. The United States has planned by 2014, to train and leave Afghanistan to handle its own problems, and to start to develop its own type of homeland defense. Unfortunately, killings such as these complicate the problem. The tension from the people of Afghanistan is rising, and people, such as this police man, are taking initiative themselves to kill our men personally. This is a whole new different scenario because before we were versing certain terrorist groups, and the people of Afghanistan were helping us out, but now we see a shift of character in the citizens of Afghanistan. Recently, men have been getting close with out soldiers and getting training by them, but then turning on them when they wont realize it and successively escaping. The United States claims that it is doing investigations for these problems, but to what point are they going to find these murderers? Instead, the United States should start either stop all training programs of Afghan soldiers or begin conflicts with these men. We are ready to leave in 2014, but how are we going to leave Afghanistan behind us?
