/You are not being sent into Germany as educators. You are soldiers on guard. You will observe their local laws, respect their customs and religion, and you will respect their property rights. You will not ridicule them. You will not argue with them. You will not be friendly. You will be aloof, watchful, and suspicious.
/Every German is a potential source of trouble. Therefore, there must be no fraternization with any of the German people. Fraternization means making friends. The German people are not our friends. You will not associate with German men, women, or children. You will not associate with them on familiar terms, either in public or in private.
/You will not visit their homes, nor will you ever take them into your confidence. However friendly, however sorry, however sick of the Nazi party they may seem, they cannot come back into the civilized fold just by sticking out their hand and saying, “I'm sorry.” Sorry? Not sorry they caused the war. They're only sorry they lost it.
/That is the hand that “heiled” Adolf Hitler. That is the hand that dropped the bombs on defenseless Rotterdam, Brussels, Belgrade. That is the hand that destroyed the cities, villages, and homes of Russia. That is the hand that held the whip over the Polish, Yugoslav, French and Norwegian slaves. That is the hand that took their food. That is the hand that starved them. That is the hand that murdered, massacred Greeks, Czechs, Jews. That is the hand that killed and crippled American soldiers, sailors, Marines. Don't clasp that hand. It's not the kind of a hand you can clasp in friendship.
/ “But there are millions of Germans. Some of those guys must be okay.”
/Perhaps. But which ones? Just one mistake may cost you your life. Trust none of them. Someday the German people might be cured of their disease. The “super race” disease. The world conquest disease. But they must prove that they have been cured. Beyond the shadow of a doubt. Before they ever again are allowed to take their place among respectable nations. Until that day, we stand guard.
