Trump at SA golf tournament: No one has gotten to the bottom of 9/11

2022 Trump claims that no one has gotten to the bottom of 9/11 as he hosts Saudi backed golf tournament and praises Saudi crown prince Salman. The same prince that had rounded up the "one side of the triangle."
"Well nobody's gotten to the bottom of 9/11. As to the maniacs that did that horrible thing to our country, to our city, to the world... There are a lot of really great people that are out here today."

Now consider all of this in the context of a possible plan to destroy the FED and the petro dollar that is based off debt and, to put it simply, a slave system. Saudi Arabia seemingly became one of Trump's greatest allies yet now they are working with Russia and China to destory the US dollar. Why? Is it just to benefit themselves or is there some larger plan at work here?
