It is suggested elsewhere that the Biden visit actually is to join with Saudi Arabia and the other nations of the NegevSummit in the effort to contain Iran.
This action is still caving because it effectively means the Iranian Nuclear deal is no longer an objective. The Biden administration has decided to actively rejoin the others that include Israel, Egypt, Jordan, Saudi Arabia and the UAE in regional close cooperation initiated by President Trump
Biden has intimated the trip is for Israel but needless to say any “I’m doing it for Israel” drama from Biden is an admission that Trump was right about his policy towards the Saudis more openly friendly.
If Joe Biden talks regional security in Saudi Arabia Joe Biden is saying out loud:
“Donald Trump Is Right”
