Just to note that Palestine is different because Palestinians are not waging an imperialist war but an anti-colonial war. This text doesn't apply to the Palestinian struggle for self-determination and Palestinian communists are correct in supporting their government even if it is not progressive or communist:

The struggle that the Emir of Afghanistan is waging for the independence of Afghanistan is objectively a revolutionary struggle, despite the monarchist views of the Emir and his associates, for it weakens, disintegrates and undermines imperialism; whereas the struggle waged by such “desperate” democrats and “Socialists,” “revolutionaries” and republicans as, for example, Kerensky and Tsereteli, Renaudel and Scheidemann, Chernov and Dan, Henderson and Clynes, during the imperialist war was a reactionary struggle, for its results was the embellishment, the strengthening, the victory, of imperialism. For the same reasons, the struggle that the Egyptians merchants and bourgeois intellectuals are waging for the independence of Egypt is objectively a revolutionary struggle, despite the bourgeois origin and bourgeois title of the leaders of Egyptian national movement, despite the fact that they are opposed to socialism; whereas the struggle that the British “Labour” Government is waging to preserve Egypt’s dependent position is for the same reason a reactionary struggle, despite the proletarian origin and the proletarian title of the members of the government, despite the fact that they are “for” socialism. There is no need to mention the national movement in other, larger, colonial and dependent countries, such as India and China, every step of which along the road to liberation, even if it runs counter to the demands of formal democracy, is a steam-hammer blow at imperialism, i.e., is undoubtedly a revolutionary step.
