were there any people thinking about Germany allying with the western allies against the Soviet Union?

absolutely; the United States. Immediately after the war, the USSR went from ally to rival within like two years. The red scare that had been around since the bolshevik revolution in 1917 had dissipated during WW2, but after that was done, it came back with a vengence. The US now needed their half of germany to be a bulwark against communism, and it needed to be economically and politically strong. Other european countries were obviously not thrilled, but couldnt really object.

I wrote a paper a few months back about the rhetoric of the holocaust after the war. Seems kind of relevant. Main source is Holocaust in American Life by Peter Novick.

Immediately after the defeat of Nazi Germany, the United States had a new foe. The Soviet Union had gone from invaluable ally to threatening totalitarian superpower, and Nazi Germany from threatening superpower to ally. Suddenly it became very disadvantageous to remind the public of the Holocaust. As Novick puts it, “symbols that reinforced the old view were no longer functional. Indeed, they were now seriously dysfunctional, reminding Americans of how recently our new allies has been regarded as monsters.” In order to accomplish this rapid publicity shift, the United States had to perform some rhetorical gymnastics. Rather than the Shoah being caused by Nazism, now it was authoritarianism. “Even active support of the Nazi program could not be considered criminal, because ‘totalitarian regimes insist [on] enthusiastic unanimity.’” Rehabilitating the German image as a friend in the fight against communism meant disregarding the entirety of the Holocaust, and in turn, this put tremendous pressure on the American Jews to disregard it as well.

Due to this rhetorical shift, the Jewish population in America was forced to disregard the Shoah as well. Conspiracy has long linked communism to Judaism, and in the age of McCarthyism, Jews were forced to confront the realities of their optics. “The popular association of Jews with Communism dated from the Bolshevik Revolution...In the interwar years the Communist Jew was a staple of anti-semetic propaganda both in the United States and Europe.” Additionally, along with the separation of Germany and Nazism, the victims of the holocaust were obfuscated as well. Rather than a purge of Jews, the goal of Nazi Germany was to remove political rivals. After the liberation, then general Dwight D. Eisenhower stated that he wanted journalists and lawmakers to visit “German camps in which they placed political prisoners.”This narrative was not only accepted by the general populous, but also a vast amount of American Jews. “It should always be pointed out that Nazi tyranny does not discriminate between Jew and Pole,” said one writer in the Zionist publication, Jewish Frontier. Jews advocating for themselves in the wake of the Shoah could be difficult during a Red Scare, and discussing the Holocaust was not adventagous for their public image. And so, outside of that brief moment of using it for political gain, the Shoah was largely disregarded for almost a decade.

Theres also Operation Paperclip, where the US was competing with the USSR in hoovering up all the nazi scientists and generals and psycho torturers (google klaus barbie for a not fun read). Cold War was a strange time
