The goal is to limit a 10,000 person epidemic now so that it's only a 15,000 person epidemic by the end of November when we finally control it. Those numbers are unrealistically low (the real numbers are more than double), but 3,000 of our people can make a huge difference, possibly enough to bring this under control if they go in the next couple of weeks.
That said, I agree with you if your concern is over whether the anti-American druggie in our White House will actually give or even approve sensible orders for our military to do what they do best safely and then step back to allow Africans to deal with patients face-to-face. We should build mobile hospitals (MASH units), with a total of 10k to 20k patient cots distributed over the areas with active disease. We can't just send the tents because Africans with too much work and too little experience with mobile hospitals would not locate them in the right spots or set them up correctly. Unfortunately, I doubt that Obama will use our forces intelligently. He has never done anything sensible since he took power, and I see no signs of him learning from his massive errors.
We?
Where's China in all this?
I seem to recall that China has been investing heavily in Africa, probably because China needs African natural resources to feed its manufacturing industry.
Let China fix the problem. China is always eager to everybody else's job, let China do the job of fighting this epidemic in Africa, too.
