Sounds like it's a problem that could be unilaterally solved by the US limiting military aid to Israel instead of propping up a genocidal regime. It's not Russia's fault that US foreign policy led to their support of genocidal maniacs.
What do people say about Russia and China? That the government and the people are different entities? The same applies here. Not supporting the absolutely batshit crazy Israeli government does not indicate a lack of support for the Jewish people.
People want revolutionaries under constant oppression and inequality to fight a "fair, modern war" against one of the most well-funded militaries in the region.
Are people stupid? Palestine, unlike Ukraine, doesn't have the privilege of fighting an equal war.
