Until now, I have not found a weak point in America, the effect of which is only deadly for the United States but cannot be exported to other countries. America has begun to build India to become an American proxy against China in Asia. America indeed plays god-level politics or indeed officials in other countries do not understand geo economy, geopolitics, and geostrategy.
Weak points against America may not be visible to all of us but power shift from America to a new country or to a new entity may happen in at any time unexpectedly. America is enjoying being a super power without any major production or they are producing only top cream level of things and not the life's essentials. Still, they are able to hold the super power status. I guess when any country which will rise due to actual economy growth then America may not able to hold its power.
There are lots of possibilities dollar to be replaced by bitcoin at least for the part of medium of exchange. I guess the powers of America may be shared by more than one entity in coming years. It will be like USA may not remain as a super power but there are other group of countries will be having that status.
