I think everybody, save for some Israeli extremists, agrees that this should have never happened. The Israeli denial of the ethnic cleansing that took place is terrible and they need to get over themselves and admit fault. The people who would come to form the state of Israel fought the British first, it’s not like they just gave up land to the Jews. In fact, up to and during WW2, the British kept down Jewish immigration to appease the Arab states whose help they needed in the war, to the point where the UN’s predecessor stepped in because that was against the terms of the mandate giving them control over the region in the first place. In true British fashion, when they saw that the area was too big of a mess to manage, and ran away, leaving the fighting powers to their own devices, and escalating the conflict.

However, when all of this went down, WW2 was over. The Palestine war and the many armed conflicts after is started two years after WW2 had gone by. In fact, the peace that followed WW2 was one of the main reasons for the British to even abandon their colonies: everyone in the UK was sick of fighting and the country didn’t have the resources to keep that many colonies under control, let alone the desire.

But now you’re advocating for uprooting millions of people from the homes they grew up in. Look at the age graph of the populations of both Israel and Palestine, the people who were actually involved way back when form a small sliver of the population. Over 700,000 people were displaced by the Zionists, but now displacing over 9,364,000 people in revenge isn’t a solution.
