I recommend a book 'Silk Roads' by Peter Frankopan. It’s an attempt to show world’s history as a continuous movement of center of civilizational gravity. It’s not without flaws, but interesting nonetheless.

Frankopan describes most of modern US history as a series of blunders. This approach is maybe a bit harsh, but it shows how difficult it is for a dominant power to stay on top.

I would summarise the book with a sentence „When you reach the top, the seeds of your decline are already planted”. In fact you can look at China or India - future dominant powers, and guess which of their flaws will make them fall.
