There are too many players with varying interests at different levels to just go off of someone's reputation and an unnamed source. Perhaps Biden or some other head of state needs to come along and blow up this thread so that moderators and commenters alike have to find other outlets for the water they're carrying.
Although if Biden took part in such a conspiracy, someone in one of the American intelligence agencies would've probably leaked it out.
They have successfully annoyed just about ever regional player, as well as the US and every other major power at times, and yet mange to thread the needle of staying friendly with the US and Iran at the same time. The way they played out the Saudi sanctions on them was a masterpiece, and they are the biggest gas exporter in the world.
No evidence they are involved of course, but there are plenty of extremely competent militaries in the Middle East.
