Why the british withdrew is closely connected as the Israeli/Zionist continuous terroristic attacks against the British and clamping down the Israeli/Arab terrorist factions warring is what was the final straw that broke the camel's back of a country already weakened by WW2. The fact of a place lacking a formal military I hope doesn't make it legal or okay by the some entity to violate their property rights, for the same could be said equally either way for Israeli illegal settlement expansions, for if there is no clear state system there, what's the objection against shooting down the squatters? (Even with a real state existing some countries have things like the Castle doctrine of course, which gives a full legal justification to shoot down the Israeli squatters). The real question that must be answered is if the locals are okay with you arriving, if you came in and legally purchased property or were granted some parcels of land with agreement by the locals, neither of which of course occurred during the violent establishment of Israel. The question of property and territory is very ancient and predates even humans, even animals have a sense of territory. So if you do not respect the existing legal claims by the British or Ottoman governments or claims by precedent of living, then you should be justly treated as an illegal invader. It is a very high degree of naked ingratitude to complain and start attacks against the Brits for controlling their own border and restricting immigration to their own lands, behaving as if these random Poles and Russians literally own the place. Would you support random Poles or Russians performing terrorist attacks against America if the USA instituted a strong and limited immigration quota upon them? Because that's what happened in the region of Israel back then. I completely understand the Holocaust but that gives a person no right to go ahead and rob at gunpoint an unrelated entity's land, moreover launching attacks against a country that bled so much fighting against nazis.
