The Afghanistan war is turning into another Vietnam...Hands are tied by political strings. Coincidentally (?), LBJ (D) got us into Vietnam, Obama(D) escalated our presence in Afghanistan, because he wanted the same success there that Bush had in Iraq with the surge. But Obama's rules-of-engagement substantially changed how and when, and under what circumstances our troops could engage the enemy, just as LBJ did in Vietnam. It's time to fully engage or get out.
