Yea, they shouldn’t be there either. How many GI’s do we have stationed in West Africa again? I can’t imagine why there are any. And, how many of them did you say had got the virus such that we needed to extract them?
As for Christian (and all other missionaries) they take their chances. They are not there on behalf of US interests. So, God can extract them from their self-inflicted peril.
If you want to block Americans and our GIs from coming home for medical care, you better figure out some way to do it, because it isn’t happening.
