Hive account@gniksivart - It's called the Thucydides Trap, where a status quo power is challenged by a revisionist power (essentially what you're saying). Roughly 70% of the time, that trap results in war.

Yes, I believe that the U.S. will go to war to protect its supremacy/hegemony in the world. A U.S. that loses its pole position is one in decline and collapse. War is the only way to extend the life of Pax Americana.
