Seriously, what Israel is doing today is no different from what the Nazis did before and at the beginning of World War II, extreme nationalism, illegal expansion, annexation of foreign territory claiming it historically belongs to them, propaganda using the latest technology, terrorizing neighbors, military at the center of society.
Because those same countries were never ideologically opposed to fascism in the first place. America was a major inspiration for Hitler, namely in its jim crow laws and eugenics. Before world war 2, America loved Hitler. And the western powers are the reason why Zionism exists as an influential ideology to begin with. Britain gave the land for zionists to colonize to begin with. All of these same countries also committed the same atrocities themselves when colonizing places like the Americas, Africa, and Asia. Liberal governments have never been opposed to colonialism, genocide, or fascism.
