Might is right, I fear.
If you go back to the UN General Assembly Resolution 181.
The UN is only a collection of member nations. Its primary role is in peace keeping, and resolutions to end conflicts.
Only the security Council Resolutions are enforceable. The resolutions of the General Assembly are only advisory.
It has no comparison with the EU, nor the US, nor the old USSR, because it has no overarching council to formulate policy.
The only semi-autonomous organ is the International Court of Justice. But the judges are appointed by the UN General Assembly.
So when we talk about the UN Resolutions we are talking about the decisions arrived at by the member nations.
In 1947 there were 51 member nations.
And the UN General Assembly Resolution 181 was passed by 33 votes to 13., There were 10 Abstentions including the UK.
Palestine was not represented and the UK did not accept Palestine being a member of the Arab League.
TransJordan was also not represented, neither was Turkey.
This is despite the population of Palestine at that time of about 650,000 Jews and about 120,000 Palestinians.
As a General Assembly resolution, it was not enforceable, but the Jews adopted it any way, and a civil war ensued in Israel/Palestine between Jews and Palestinians. The UK were in the process of removing themselves from the region, and were expected to perform a peace keeping role.
So one could argue that the Jews invaded Palestine, because the Resolution was not enforceable, but the Jews enforced it anyway.
Indeed a communication from Ben Gurion stated:
The Arab League had also stated their objection to the Resolution and stated that they would violently resist it if it were passed.
The UN (the collection of the 51 members), Palestine (transjordan) was not represented, nor was Israel because it did not exist, the UN passed the resolution in the full knowledge that a conflict would ensue, and in denial of the UN founding principle of self determination by countries.
So a civil war between Jews and Palestinians ensued. (Between November 1947 and May 15 1948)
At the end of the civil war, the Arab League declared war on Israel., May 1948) just hours after the UK left, and Israel had declared its existence and independence.
During the early months of the war between the Arab League and the Jews, now Israelis, there were several attacks on Palestinian civilians which motivated the Nakba. the mass evacuation of Palestinian refugees. About half of the Palestinians population were displaced.
Also during the first two years of the conflict there was a mass migration of Jews to 'the newly declared' independent Israel, from various countries around the world.
So one could be forgiven for perceiving that Israel was borne out of conflict, and not much else.
It has continued to exist through violent conflict and has been supported ever since through violent conflict.
Might is right.
