If you could go back to 1938, and had ONE CHANCE, using a bomb, to kill Hitler when he was surrounded with children, would you do it?
If you did, he today would be known as one of the greatest unifiers of Germany until he was “murdered” in 1938.
I'd set my time machine to WWI, way before 1938, and find Adolph in the midst of battle and lob him a good one with his name on it.
That way millions of people would have been spared their lives.
