As this was 'Pre-Israel' then I do know that there Palestinian Jews fought alongside the allies within the Jewish Brigade and other regular units and that it was supported by the Yishuv, but did the Palestinian Muslims also fight alongside the allies?
Just like there is no homogenous Jewish voice (the Jewish Agency was one of many competing views of Zionism), there is no homogenous Palestinian voice when it came to WW2. Just wanted to make that clear.
I've been seeing too many articles and posts in Reddit, that lumps everyone and their competing ideologies and beliefs into "two" camps: Jewish and Palestinian. Fact is that did not exist; and just as you had Palestinians who worked with the Germans (Haj al-Amin Hussieni) you also had Jews who worked with the Germans (in the early days) to get Jews to Palestine, by smuggling them past the British blockade. This is not a black and white affair.

During the British occupation of Palestine, the Irgun (Jewish 'anti-colonial terrorist' group) initially sided with the Allies to fight against the Axis with the promise of independence and own government following the war.
Also, there were Arabs and Jews who joined the British Army during WWII, known as the Palestine Regiment. The Palestine Regiment was part of the British Army and fought in Egypt and Libya.
So kind of.
The state of Palestine was under British control at the time, so to say that Palestinians were against the Nazis is historically true because Palestine was a British colony until after WWII.
