Here's the deal.
Yanks alone - with only 320+ m ppl don't have the necessary strength to be the "only superpower".
They can pull it off coz they got many poodles, minions, stooges, puppet regimes.
From Al Saud regime bankrolling the petrodollar - the Al Saud and other GCC Arab Dictatorial regimes require that any oil/gas purchased from them be paid for with US$ - to the Japs, Gooks and other slanties, yanks got poodle regimes all over Europe, Asia, Africa, Latin America, Canada, Australia.
Their combined population well over 1.5 billion ppl (minimum) plus 100's (plural) of trillions (with a T, not B not M) of $, € £ or equivalent in other currencies in resources, plenty of land and all the natural resources incl water sunlight wind agricultural land scenery sights, land for manufacturing, for residences, for work, play, nature reserves, for aviation, for trekking for all sorts of activities. incl space flight, flying as a hobby, hunting (animals or birds) or becoming a recluse in the jungle or a cave in the mountains - things you simply can't do in teeny tiny dot sized stinkypura for example. stinkypura really is a pathetic one party state dictatorial dynastic sh*thole sinking further and further into the abyss
Tiongs only got population. Their natural resource is population. All of their achievements are also dependent on population. Remove population from the equation, Tiongs have achieved very little.
Yankees - by themselves - without their minions, poodles, stooges, puppet regimes that they call their allies and/or partners, simply do not have the numbers to be the "only superpower".
That is the deal.
How can Tiongs replace Yankees?
