The US has a democracy i.e. the government represents the people. If you're a citizen on the US you can protest/resist anything you want, apart from in very extreme circumstances.
During World War II, actions such as criticizing the government, protesting against the war, or refusing to support war efforts were considered unpatriotic. Public sentiment strongly favored support for military actions, and dissent was often met with suspicion or hostility. Additionally, failing to buy war bonds, hoarding goods, or not participating in rationing efforts could also be viewed as unpatriotic, as these actions were seen as undermining the national effort to win the war.
Yes It is unclear what is meant by "Palestinian Involvement". The Jewish Militias of Palestine, like the Haganah and Palmach (who at that time were called Palestinian Jews) actively contributed to the British War Effort against the Nazis. The Palestinian Arabs did not assist the British War effort, although they were involved in supporting the Grand Mufti of Jerusalem who was a close friend of the Nazis and Fascists in Europe.
The answer depends upon whether the war is just or not. Sometimes war is unavoidable and necessary. If the war is just and one protests against it that person is unpatriotic. However, a person might still value religious or moral or personal views higher than patriatism. Protesting unjust wars is not unpatriotic. Clearly the key is to know what is just and unjust. I would submit that there are clear cut cases of just wars such as WWII. Unjust wars are usually much more difficult to judge, especially at the time that the conflict took place.

The Committee on Public Information (CPI) portrayed anti-war individuals as unpatriotic to foster a unified national sentiment during World War I. By framing dissent as a threat to national security and morale, the CPI aimed to suppress opposition and rally public support for the war effort. This strategy helped to instill a sense of duty and loyalty among citizens, which was crucial for maintaining enlistment and financial backing for the war. Moreover, labeling dissenters as unpatriotic served to marginalize their views and discourage public debate.
