Surprisingly enough, there were a statistically significant number of jews that served in the National Socialist regime, even in the military. Many jewish intellectuals were already well integrated into Germany, and some joined the Fascist movements generally, and a few were prepared to support the National Socialists as germans, rather than as jews. There was still a debate among National Socialist race scientists about how you support germanic "blood" when it's mixed with jewish "blood". There was a lot of confusing arguments about how you could control their breeding to separate & recover the germanic blood from the jewish blood down the line.

Because of that, you do find jews that are National Socialists, and some that even serve with distinction in the Wermacht. Now, Hitler would go on to start purging them more by the mid to late 40's after the war started to go badly, but you still would have found a few jewish National Socialists in Germany. There were thousands of jewish Fascists in Italy
