It was never a reasonable timeline. Modern history is essentially the present population waking up to the crimes of past (and present) generations, including their direct ancestors.

Israel was created by colonial states committing colonial-minded crimes, during the near-total collapse of colonialism immediately following WW2. England had assumed control of "Mandatory Palestine" after the Ottoman Empire fell with WW1. Through the League of Nations — dominated by colonial powers, like the UN is to this day — they essentially annexed land they had no legitimate ownership of, denying the population of Palestine their basic human rights to democracy and self determination, and gifted it to millions of refugees who were not even born in that location, and held no reasonable claim to that land (beyond ancestry from hundreds/thousands of years ago, that never made up more than a minority of the people who lived there).

It would make more sense, and be more logically and legally justifiable, to give the USA, Canada, and Australia to their indigenous populations in 2024 — who 100% owned those lands up until the last few hundred years — than to give Palestine to the Jewish population in 1946.

Similar crimes happened in South East Asia and Africa post-WW2. For example France trying to militarily reclaim Laos and Vietnam (backed by the USA). Both the Vietnam war and Cambodian genocide may have never occurred if those countries were allowed to implement legitimate democracy.
