I think th United States doesn`t need to train that people. A lot of people die because of that.  These graduates have consistently used their skills to wage a war against their own people. It is very crual also to take people and to make them kill their own families and people from their own country. That people don`t want to kill their friends and destroy the contry they grew up. It`s in their hearts.
I think U.S doesn`t need that armies.
