The middle east is not a mess. You have got it wrong. Like Biden, you are attempting to play a game that is already over.
Donald Trump ended the mess with the Abram accords. Israel and the Arabs are now working together to oppose Iran.
Recently the Negev summit resulted in serious economic cooperation between the Arabs and Israel. The UAE, Egypt and Jordan are clearly increasing trade with Israel. Saudi Arabia is not close to Israel economically because of internal politics but is close ally militarily. I suspect that Israeli products can be imported into Saudi Arabia via the UAE
The Palestinians have been deserted by the Arabs who finally concluded there was no upside to supporting what amounts to a cancerous tumor.
The middle east is quite stable and is very far from being a mess
The middle east is not a mess.
________
The middle east is run by bunch of dictators and strongmen.
None of them has clean hands.
What I am saying is that Trump choose the lesser evil and it was the great choice.
Biden is trying to undo it, which is huge mistake. They now seem to seeing that too!
