The US has been the sole world policeman since the fall of the Soviet empire in the early ’90s. It has relied on its economic might as well as the ability to project power militarily anywhere on the planet through an advanced and well equipped military as well as strong and compliant allies.
Lately though, US President Trump has alienated most of the traditional US allies even in the west. Most of the consumer goods the US needs are manufactured in China. The US owes China trillions of dollars. The US has been clearly in decline.
China on the other hand, through the Belt and Road Initiative, is now able to project its economic might across the globe, even in Europe. Has it overtaken the US as the sole global superpower?
