—“If you were the President, and you wanted to destroy America’s power in the world and unity as a nation, what would you do?”—

This assumes American power is good thing (empirically, we have pretty much always been wrong in every single conflict). And it assumes it’s not a good idea to withdraw from the burden of continuing the British Empire’s network of finance and trade despite having dragged humanity kicking and screaming out of ignorance, poverty, and disease in the face of competition from marxism, communism, socialism, and its modern variation: islam.

We are no longer asymmetrically advantaged either technologically, economically, or militarily, and we have even lost our demographic superiority through vast underclass immigration.

So while the minds of children make moral and emotinoal judgements, those of us who have adult minds make empirical judgemnts.

The answer is pretty simple: we can’t finance the world transformation from superstition to empiricism any longer because enough of the world has adopted our aristotelianism (empiricism, science, technology, law, markets) that it has been costing us quality of life since the 70’s.

in other words, VIRTUE SIGNALING SO THAT YOU FEEL GOOD ABOUT YOURSELF IS NO LONGER AFFORDABLE.

But to answer the question: I would create power vacuums as did Obama and Carter rather than demand vacuums be filled by depriving other countries of subsidies.

But this requires you understand not only economics, but capital. And strangely enough, mainstream (saltwater) economics, does not measure capital changes, only consumption.
