The era of colonization has ended though. The imperialists could have just as easily influenced a Palestinian state, like they have done with the gulf states and Ukraine, Taiwan, and the Phillipines to bow to the empire. Notice how the imperialists didn't import an entire ethnic group into those countries, they just imported their ideologies.
They already did it with the Palestinian Authority, any country that shows the slightest pushback against the imperialists gets blown to pieces or overthrown. See Libya, Egypt, Iraq, Lebanon, Syria.
Why prop up a colonial entity when we've moved past that stage of imperialism? The masses became "woke" to colonialism post-WWII and most imperialist countries instead have a way to make their evils less transparent in their ways of controlling another country's resources. Color revolutions, "soft-power" via predatory IMF loans with clauses demanding for privatization of infrastructure are ways to name a few.
Why go through all this effort manufacturing fake historical justifications for why this type of colonization is good, when they already have the gulf states and the Palestinian Authority as loyal servants to the empire?
Edit: even the Xinhua Institute says pre-WW2 colonization is dead. Enough with the vibes-based analysis.
