I largely agree with what you’re saying, but I think the idea that Israel was established because of Hitler is not entirely accurate (and not entirely wron either).

First off, zionism was conceived as a solution to the rampant antisemitism in Europe (not just Germany), well before Hitler even left elementary school. It was intended to be a colonial project, so they looked for the help of colonial powers like the Ottomans and the UK. They ended up choosing Palestine as a good location, and the UK (which was occupying Palestine at the time) formally agreed to an establishment of a Jewish state in Palestine, already in 1917 (Balfour declaration). At this point, Hitler was in the trenches of WWI, and no one had even really heard of him, so it is unlikely that he was a factor in the drawing up and signing of the Balfour declaration.

Secondly, the first wave of jewish colonizers (30k ish) arrived between 1881 and 1903. This is around the time Hitler was born, and I’m willing to bet he didn’t play a big part in them moving. They were fleeing the pogroms.

Until then, the local arab and jewish Palestinians had been co-existing in relative peace, as regular neighbors. The arrival of the jewish colonizers led to a cycle of violence of colonizers attacking the natives and vice versa. This culminated in the forming of jewish terrorist groups Irgun, Hagana, Lehi, and others, which carried out bombings, murders, and sabotage. A famous example is the Deir Yassin massacre, where Hagana killed 100-200 Palestinian villagers. Near the end of WWII, these terrorist groups were also increasingly attacking the British, seeking the establishment of an independent jewish state.

It was this context in which resolution 181 was drafted, in 1947. Of course, the holocaust was a major factor in its adoption, but the resolution itself was a direct response to the violent conflict between the jewish colonizers and the native population, and the insurgency of the colonizers against the British.

Next, I’m not entirely in agreement with the idea that Israel became the madman. As you can see from the terrorist groups I mentioned, the colonizers were already violent even before the eatablishment of Israel. After the establishment, it immediately became much worse.

Upon its creation, Israel was given 55% of the land despite making up only 33% of the population. As a result, a large portion of the native population had to be removed. They did this by destroying entire villages, about 500 of them, and carrying out numerous massacres. About 700k Palestinians were removed from the region. There’s a technical term for this: “ethnic cleansing”

For the next 75 years, Israel would continue the violence against the Palestinian population. Notable events were the 1967 war, which resulted in the ethnic cleansing of close to another 500k Palestinians, the Sabra Shatilla massacre, where 3500 refugees were murdered in one night, the break-their-bones policy which involved rhe whole scale torture of protestors, and so on.

There has never been a point in time where Israel was not a violent aggressor. The only difference today is that it’s harder to hide on account of social media.
