Saudi Arabia’s de facto ruler Crown Prince Mohammed bin Salman said every day was bringing him closer to a deal with Israel.
Israel’s prime minister Benjamin Netanyahu openly talked of such an outcome in his address to the UN General Assembly in New York a month ago.
The US president could dream of a historic handshake on the east lawn on the eve of election year.
Instead he is looking at war in Israel and Gaza, with another much bigger one a real possibility, and all that means for the chances of global recession.

He will try to add weight to that four-letter warning that he has already given Israel’s enemies thinking of joining in.
“Don’t”. That includes two naval carrier groups and US marines in the region in force.
And he comes with a message to Israel. We have your back but do not overreach. A bloodbath in Gaza will inflame passions and tensions in the region.
America’s diplomacy has failed in the Middle East not for the first time. It must now work overtime to stop a bad situation becoming much, much worse.
