trump wrote nothing ever, and read even less. He was duped by Jared and the Saudi "royal" family into backing the right wing Israeli effort to stoke Shia/Sunni conflict in the region, their ambition being to be on the majority Sunni side in a conflict that deflected Muslim combativeness away from Israel.
The new Saudi/Iran rapprochement shows that both have remembered who their main enemy is and looks to sink Israel's desire to stand free of the conflict.
Hard to know whether trump was compromised by his desire to dig up dirt on Biden, his history of laundering money for Russians, but by his actions it's clear that he was willing to work for putin.
