If they try to migrate, and they will. Ebola will spread. How about telling any that try to come here by boat/plane/etc. That if they get within x amount of miles, they will be sunk/shot down, etc.
Perhaps people who try to leave should be shot and their bodies burned? We are sending our soldiers into this mess? Why? Symbolism? For the November election? Why? Why do Americans put up with this? What happens if 20% catch Ebola?
