USA

Although policies against fraternization were instituted for the Americans in Germany, the phrase "copulation without conversation is not fraternization" was used as a motto by United States Army troops. The journalist Osmar White, a war correspondent from Australia who served with the American troops during the war, wrote:

After the fighting moved on to German soil, there was a good deal of rape by combat troops and those immediately following them. The incidence varied between unit and unit according to the attitude of the commanding officer. In some cases offenders were identified, tried by court martial, and punished. The army legal branch was reticent, but admitted that for brutal or perverted sexual offences against German women, some soldiers had been shot – particularly if they happened to be Negroes. Yet I know for a fact that many women were raped by white Americans. No action was taken against the culprits. In one sector a report went round that a certain very distinguished army commander made the wisecrack, 'Copulation without conversation does not constitute fraternisation.'
