I don't think you understand that the partition plan entailed not a single Arab having to move.
Am not sure what this has to do with anything? are you denying that after the majority of Palestinians were displaced Israel destroyed their homes and their villages and refused them entry? and if indeed no Arab had to move then why were people escaping warfare not allowed back?
in what world is a colonialist state allowing a token minority of indigenous people to stay commendable?
Moreover you are confusing multiple things here, most importantly though is the goal of the Zionists and their discourse and the Partition plan, the partition plan is not what the Zionists wanted but what they managed to get.
Ben Gurion speaking about partition once said in a letter to his son:
A partial Jewish State is not the end, but only the beginning. ... We shall bring into the state all the Jews it is possible to bring ... we shall establish a multi-faceted Jewish economy - agricultural, industrial, and maritime. We shall organize a modern defense force, a select army ... and then I am certain that we will not be prevented from settling in the other parts of the country, either by mutual agreement with our Arab neighbors or by some other means. Our ability to penetrate the country will increase if there is a state. Our strength vis-a-vis the Arabs will increase. I am not in favour of war ... [but if] the Arabs behave in keeping with [their] barren nationalist feelings and say to us: Better that the Negev remain barren than that Jews settle there, then we shall have to speak to them in a different language. But we shall only have another language if we have a state.
The refugee situation occurred when much of the Arab world - including many Palestinian leaders and soldiers - launched an aggressive war to eliminate Israel.
Hundreds of thousands of refugees were created before 'much of the Arab world' set foot in Palestine, in fact one of the reasons listed behind their involvement was to stop further displacement of Palestinian people. By the time the Arab armies attacked Israel had occupied far more than what was allotted to it in the partition plan.
Also 'aggressive'? how are people defending themselves against a conquering militarily superior foreign colonial movement aggressive?
Their reaction hardly unique, as Walid Khalidi said
"The native people of Palestine, like the native people of every other country in the Arab world, Asia, Africa and Europe, refused to divide the land with a settler community."
Lets quote Ben Gurion again (in
1937):
In our political argument abroad, we minimize Arab opposition to us. But let us not ignore the truth among ourselves. I insist on the truth, not out of respect for scientific but political realities. The acknowledgement of this truth leads to inevitable and serious conclusions regarding our work in Palestine… let us not build on the hope the terrorist gangs will get tired. If some get tired, others will replace them........When we say that the Arabs are the aggressors and we defend ourselves — this is only half the truth. As regards our security and life we defend ourselves and our moral and physical position is not bad. We can face the gangs... and were we allowed to mobilize all our forces we would have no doubts about the outcome... But the fighting is only one aspect of the conflict which is in its essence a political one. And politically we are the aggressors and they defend themselves. Militarily, it is we who are on the defensive who have the upper hand but in the political sphere they are superior. The land, the villages, the mountains, the roads are in their hands. The country is theirs, because they inhabit it, whereas we want to come here and settle down, and in their view we want to take away from them their country, while we are still outside. They defend bases which are theirs, which is easier than conquering new bases... let us not think that the terror is a result of Hitler's or Mussolini's propaganda — this helps but the source of opposition is there among the Arabs.
Of course they have the moral and just position in as much other colonialists had morally justified their own movements.
The Zionists had little intention of creating an apartheid state. 25% of Israeli citizens aren't Jewish but are afforded the full rights and privileges of Israeli Jews.
Actually they wanted to create a Jewish state in all of
Palestine regardless of the wishes of its native inhabitants who they didn't even bother with initially and were forced to acknowledge eventually, and long before they even made up the 32% they did on the eve of its creation, they of course weren't allowed to do that and had to compromise at least in public but never budged about the nature of their state. The only viable options left for them were the ones they went with, that is displacing the majority of Palestinians and not allowing them back in ever since while keeping a small minority so that their state could remain 'Jewish and Democratic'.
Finally there's the issue of the Partition Plan, it being unjust notwithstanding, just a couple points:
1- It is not legally binding, its a mere recommendation that requires the agreement of both parties to be of any substance, just like the many resolutions Israel ignores today for example the one you know where it is asked to take back the refugees.
2- Its is not the first one to suggest partition, there was another one in 1937 which Zionists refused because it didn't give them enough lands though they were ecstatic about the part that suggested forcible expulsion of Palestinians. So if Zionist colonialists are allowed to refuse partition (at a time when Jews were being persecuted in pogroms around Europe) because it doesn't give them enough territory how come Palestinians are blamed for refusing partition when the partition plan in 1948 gave the colonialists who made up a third of the population more than half of the same territory?
3- The Arabs proposed creating a secular state with equal rights which was refused by Zionists, how come should their insistence on establishing an exclusivist Jewish state in other people's lands and refusing the Arab offer is not subjected to more criticism?, but the native majority refusing partition of its land is?
4- The Arabs asked that the issue be referred to the International Court of justice multiple times, and they were turned down.
