You sound like quite the inspirational guy, our GIs stationed in Africa and our Christian missionaries and CDC workers don’t rank very high on your scale.
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.
