Israel is, to all intents and purposes, the last European colony.
I don't think colonies were allowed to conduct their own foreign policy, develop nuclear weapons in secret or carry out infowar operations inside the metropole.
Israel has an intentionally nebulous relationship to the West. Like many, many aspects of Israeli policy there's a bit of a paradox going on, because Israel likes to strategically present itself as a secular Western aligned country while also pointedly rejecting Western liberalism and pursuing policies which isolate it from many European countries and populations.
However, with typical imperial arrogance, they decided some other poor sods - the Palestinians - could make way for it.
There is a massive blind spot in early Zionist thought when it comes to the population already living in Palestine. The general assumption is that since European Jews were a relatively wealthy minority they could simply buy the land and everything would be fine. The people selling the land will get a good deal and be happy, and they can use that money to move somewhere else and buy new property.
The problem is that Palestine was part of the Ottoman Empire. Its agricultural system was still basically medieval and much of the population were tenant farmers working for predominantly Turkish landlords. When the Empire collapsed after World War 1, those landlords saw the writing on the wall and left. Thus, ownership of the land became disputed.
This meant that when Zionist organizations moved in and started buying up the land, they were often buying from absent landlords who hadn't set foot on their property in decades. The tenant farmers who were working the land and were pretty used to not having landlords didn't get any of the money, and thus were thus put in the position of losing their livelihoods with no compensation because some Jewish guys showed up one day and claimed the land was theirs now. This naturally caused conflict and resentment which escalated very quickly.
Western countries were generally pretty ambivalent around the creation of Israel. We have this narrative of the US as being 100% pro-Israel from day zero, but much of the US government was incredibly aware of how fucked the situation was. Meanwhile the British had just fully checked out and just wanted to leave before these people started killing each other.
