No, it really wouldn't. Not even a little bit. Why? Because "invading some African countries" would destroy our relationship with other countries, give the usual aggressors an excuse to continue to pursue their own invasions and probably not actually even help anyone. You don't really even have to invade, it's not like these "African countries" would mind a horde of doctors and health care workers to help them out of this horrible situation.
