I heard about the fall of Saigon while driving from Gelnhausen to Frankfurt in West Germany. I pulled over into a Snell Imbiss parking lot. I set there, alone, for a very long time. Tears were shed and I thought of all of my friends and soldiers who did not come back. We could have had a different outcome.
I don’t know what would have changed the outcome, but it certainly was a worthy cause - and the tens of thousands fleeing in 1975 and afterwards are vindication of that cause.
