Who do you think is going to stand at the borders to keep these people from moving! If you think this is a humanitarian venture, I think you need to read between the lubes.
Obama is NOT sending the military there to secure their borders. He is sending them there to do "humanitarian" work. The only way to keep these people quarantined is to shoot them if they try to escape. Obama won't give our soldiers in war zones rules of engagement that allow them to shoot people who are shooting at them without Pentagon approval, and you think our military will be used to control people in these hell holes?
Put down the bong.
What do you think it is, if not that?
