Let me get this straight. Some people help Americans fight extremists and so the extremists want to kill them. Okay, why are they helping Americans? Could it be that they care about their country and want liberty to prevail? Are they going to advance that cause by leaving? Certainly they don't agree with the extremists...their actions oppose extremists after all. Why not take that a step further and get with the other translators and like minded people, get some weapons, and go kill some extremists? Why cut and run?
If you want to help those who put their lives on the line for your country then help yourself by killing the enemy before they kill you. It just makes sense. That guy said someone told him that bad men are looking for him. Okay, describe them. Where do they live? Etc...
