However for many of those who live outside of USA, overseas where the US military operates, we understand that power vacuums are very potent and if not for US, some other country will fill the void, with soft or hard power. It’s not just China and Russia; its also Turkey and Iran, for example.
We don’t have much for a frame of reference, but I’ll tell you that the this era of Pax Americana, spanning WWII until today, has been, more or less, heavenly. Free trade and democracy have been sprouting everywhere, and under the US military umbrella and peace keeping, many nations were able to divert resources into developing their societies, not worried that they’ll be plundered by some aspiring empire.
