I presume that fascism still starts a war in Europe, but without the batshit insanity of Hitler, their gains are more modest and their defeat takes longer. Hitler’s worst move was pissing off Stalin; a rational German leader would have maintained neutrality and focused on conquering continental Europe, which they could have done by and large even if keeping it would have been challenging (evidently Nazi Germany was a bureaucratic nightmare internally; their survival would have depended on how well things were run back home.)
Meanwhile, fascism still gets a bad rep for what Japan does - people would say, “those Germans grew their lot in with the Japanese, and look what those people did.” I have no doubt there would be German atrocities, but nothing on the scale of the Holocaust; Japanese atrocities would be viewed in a worse light, and odds are Japan would have been made to pay for what they did more thoroughly. Today it would be highly Americanized and almost certainly a republic, and I wouldn’t be surprised if Okinawa was still a US territory. I wouldn’t even be surprised if Christianity was the dominant religion or at least as common as it is in OTL South Korea.
Fascism would fall out of favor but pop up here and there, and whatever flag the Germans fly as their fascist flag would probably be allowed and used by far-right parties.
Israel might be a loser in this situation, since it was the Holocaust that was a catalyst in its creation. It wouldn’t have that massive national scar and may exist in a smaller form.
