>The system established after WWII no longer serves the interests of its main creator
I don't think that's true. The policy of alliance building and containment of their largest peer and competitor still makes sense. It was how the US ultimately overcame the Soviet Union, and is even more vital given the size and talent in China. A US without an alliance system will not win that competition.
What's much more concerning is that the rational interests of the US as a nation aren't reflected in its policy making any more. The 20th century had its share of domestic issues but the inmates weren't running the asylum as far as foreign politics was concerned which was coherent.
