Reading about the current events got me looking into the history of Palestine and Israel, and I noticed a lot of Israel's politicians (like Yitzhak Shamir, Menachem Begin, and Ariel Sharon to name a few) were Zionist terrorists (using the word literally, not subjectively) since before the establishment of Israel. The groups they belonged to, like Haganah, Irgun, and Lehi have been designated terrorist organizations by the United Nations, British, and United States governments, and
Albert Einstein, in a letter to The New York Times in 1948, compared Irgun and its successor Herut party to "Nazi and Fascist parties" and described it as a "terrorist, right wing, chauvinist organization".
The Zionists have explained their view as follows:
Neither Jewish ethics nor Jewish tradition can disqualify terrorism as a means of combat. We are very far from having any moral qualms as far as our national war goes. We have before us the command of the Torah, whose morality surpasses that of any other body of laws in the world: "Ye shall blot them out to the last man."
and
Late in 1940, Lehi, having identified a common interest between the intentions of the new German order and Jewish national aspirations, proposed forming an alliance in World War II with Nazi Germany.[22] The organization offered cooperation in the following terms: Lehi would rebel against the British, while Germany would recognize an independent Jewish state in Palestine/Eretz Israel, and all Jews leaving their homes in Europe, by their own will or because of government injunctions, could enter Palestine with no restriction of numbers.[32] Late in 1940, Lehi representative Naftali Lubenchik went to Beirut to meet German official Werner Otto von Hentig. The Lehi documents outlined that its rule would be authoritarian and indicated similarities between the organization and Nazis.
It just gets worse the more you look into it, but it does give important context to the current genocide in Gaza, and to the decades old conflict in general.
Isn't this true of most countries?
Yes but in different ways depending on the country. The U.S has a pretty clear analogue, the Native American genocide.
The main difference between Israel/Palestine and the U.S/Native Americans is the former is happening currently, the U.S has already successfully completed the genocide on their natives, while Israel is in the middle of its extermination.
Germany also clearly has the Jewish Holocaust, but they weren't successful in WW2, so that genocide didn't get white-washed and instead was shamed to paint a clear good guy/bad guy narrative, despite the Nazis open praise of the U.S for our successful extermination of the natives, U.S business interests aligning with Nazis before and during the war, and the U.S trying to stay neutral between the Allies and Axis powers until Japan forced the U.S into action.
Of those that came in contact with Europeans yes, I think so, but I'm not sure how, for example, the Lakota people came to be on the land they were before they came in contact with Europeans.
