"Israel" was formed as a general western settler colony in Palestine using common british colonization tactics [III] because this region is a bridge between Africa and Asia, with companies literally named "Colonization Commission", "Jewish Colonial Trust" and the like. And has been functioning mostly as US colony since, serving its imperialist interests in the region (against Syria, Iran, Yemen, etc).

Theodor Herzl, founder of the colonial ideology he called "zionism", was himself also just a racist colonizer by his own admission, and saw it as bringing ‘civilization’ to ‘barbarians’ as the rest of Europe did when they were colonizing and enslaving Africa and Asia:

“We should there form a portion of a rampart of Europe against Asia, an outpost of civilization as opposed to barbarism. We should as a neutral State remain in contact with all Europe, which would have to guarantee our existence.” Source [II]

Only difference now is that the US has been the de facto leader of the imperial core since WW2, no longer UK in Europe.

As for republicans, if you pay attention to the extreme anti-China rhetoric from Tucker Carlson, Trump, etc it's pretty clear what they're trying to do. Allying with China against the USSR on Kissinger's recommendation was a large contributor to its overthrow, and it makes sense they want to do that against China now, what with both the US and Russia now being capitalist states.
