The United States contented itself with declaring that OPEC's decision to cut oil production is not advisable at the present time!!!

I can clearly see how the intensity of the American statements has changed from the previous one. It seems that Saudi Crown Prince Mohammed bin Salman is not satisfied with the Americans and is trying to get rid of the American hegemony.
Are the US authorities no longer in control of the global situation?

So far, we cannot say that, but I think that the signs have begun to increase clearly, and there is a great common desire among many countries to get rid of the US control over the global situation. There are many countries, including Saudi Arabia, that are not satisfied with the policy of the United States of America.
