This is the quintessential American project, the U.S. has invented and developed the oil industry in Saudi. Saudi Aramco was originally the "California-Arabian Standard Oil Company".
I don't know why this hasn't happened during the last 40 years where Iran has always been an enemy, Saudi Arabia has always been an ally and the U.S. has always had enormous amount of access to the Kingdom for the purpose of building oil infrastructure.
1 — The United States of America and the Islamic Republic of Iran and their allies in the current war are signing this MOU to declare the immediate and permanent termination of military operations on all fronts, including in Lebanon, and undertake from now on not to initiate any war or any military operation against each other, and to refrain from the threat or use of force against each other, and ensuring the territorial integrity and sovereignty of Lebanon.
But Israel has continued to attack intensively in Lebanon, killing dozens (if not over 100 since the MOU was signed, not sure), and continues to have a sizeable invasion force in Lebanese territory. Lebanon was explicitly and specifically mentioned to stress its significance - it is the country suffering the most right now, with hundreds of thousands of internally displaced due to threats from the Israeli forces against the civilian population of the south.
With that being the case since day 1, the MOU cannot be said to have even gone into effect. Certainly, the closure of the straights should be seen in this light, rather than a violation.
