The two men here are Nazis.
The one on the right attained the rank of Major in the SS and was responsible for a weapons program that terrorized England, killing over 9,000 civilians and over 12,000 slave laborers used to make his weapons.
He was known to go to concentration camps to personally pick out the slaves who would work on his weapons, since they had a tendency to blow up and kill their makers during the building process.
The Allies hated this man so much that they risked the lives of thousands of pilots and sent almost 600 aircraft to bomb his research facility in an attempt to kill him and his associates and stop his work.
At the end of the war, he schemed to be captured by the Americans because he knew the Russians were more brutal with prisoners.
In an attempt to immigrate to the United States, he lied about his Nazi party membership and work within the SS on several occasions.
Eventually, the United States Army and other government officials worked to hide his Nazi past and bring him to the United States because he was deemed somewhat valuable for our government.
Wernher von Braun is known in America for his work on the Saturn V Rocket, which helped the U.S. put men into space and men on the Moon. There are buildings at NASA, craters on the Moon, and many other things named in his honor.
We allowed a man that should have been tried as a war criminal to immigrate to the United States because his experience in murdering people with rockets proved valuable to the military and eventually the space program.
Yet decades later we would refuse to allow thousands of otherwise innocent refugees from Syria and the Middle East the same privilege on the account that there might be a terrorist or two among them?
If Christ was hidden among the crowds leaving their homes, would we still refuse them all?
We have a responsibility to our fellow man. We are more likely to turn an enemy into a brother if we welcome them and suffer with them. Or we can create future generations of enemies by turning them all away in their most desperate time of need.
