There's been antagonism between Saudi Arabia and the Persians for generations - and the US/EU/NATO is giving Iran little choice besides the RF. Their use of Hezbollah is not an indicator of strength.

Israel is giving them little choice other than to attempt to nuclearize.

Personally, I think Biden, once Bonesaw refused to take his call, should have immediately called Trehan, offered to drop US sanctions in return for oil sent to Europe and not interfering with shipping in the Strait of Hormuz; let the Saudis stew in their own juices, call Biden to see if increasing production might guarantee availability of US military hardware and parts.
