RANDOM:
What if annexing the W. Bank was a back room deal with Trump as the proverbial booby prize for giving up US foreign aid?
Bibi get's to declare, "We are independent"
Trump get's to declare, "No more aid for Israel"
Both look like winners to their respective "most ardent" bases, no?
Trump (he cares) get's to say he brokered peace.
Bibi (doesn't care) because nothing is truly lost if it falls apart (Israeli "Arab" peace hasn't been around long enough to have had some monumental impact on Israel - so losing it is basically irrelevant.
Gaza get's rebuilt one way or another - a win for everybody (Israel, US, Egypt others…)
Just a thought.
