certain enlisted personnel at risk or if enlisted soldiers believe that their selection for a perceived suicide mission is not motivated solely by a coldly impartial assessment of military strategy (to sacrifice some units so that the force as a whole will prevail), the enlisted soldiers may fail to provide the unhesitating obedience necessary to the realization of that strategy or may even attack their superiors. The Christmas Truce was a notable instance of fraternization in World War I. Allied occupation of Germany To impress the German people with the Allied opinion of them, a strict non-fraternization policy was adhered to by General Dwight Eisenhower and the Department of War during World War II. However, because of pressure from the US State Department and Congress, the policy was lifted in stages. In June 1945, the prohibition against speaking with German children was made less strict. In July, it became possible to speak to German adults in certain circumstances. In September, the policy was abandoned in Austria and Germany. In the earliest stages of the occupation, US soldiers were not allowed to pay maintenance for a child they admitted having fathered since to do so was considered as "aiding the enemy". Marriages between US soldiers and Austrian women were not permitted until January 1946 and with German women until December 1946.

The War Office notably published that German women "will be willing, if they can get the chance, to make themselves cheap for what they can get out of you" in its handbook distributed to soldiers stationed in Germany. In spite of the ban, soldiers still knowingly had contact with local women, especially civilian employees. Field Marshal Bernard Montgomery, Eisenhower's counterpart, was against the ban, and it was lifted in July 1945. Education Many schools and universities prohibit certain relationships between teachers/lecturers and students to avoid favoritism, coercion, sexual harassment, and/or sex crimes enabled by the teacher's position of authority. The prohibitions are controversial, however, as they may come into conflict with rules on tenure, for example, if unethical conduct is suspected but not confirmed. Workplace Court decisions in some US states have allowed employers a limited legal right to enforce non-fraternization policies among employees, forbidding them to maintain certain kinds of relationships with one another. Since the 1990s, such corporate policies have been increasingly
