The military is there to protect us from threats foreign and domestic. Ebola is the biggest threat out there right now.
It is. Also it is fairly easy to deal with given the right infrastructure. The countries involved do not have the infrastructure to fight it quickly. We can build that infrastructure quickly with a low risk to our soldiers.
Military threats. There is no military threat requiring troops in Africa. Let Africa, UN, peace corp and related organizations deal with it ... or not. The worst thing we can do is facilitate travel back and forth by thousands of people to that hellhole which will spread the disease to the US mainland.
