I guess the next 1-3 decades will bring a lot of change especially to the USA. What made the U.S. so strong is that everyone in the world used their systems, e.g. communication, payment system, currency, military/weapons, alliances, etc. But I think no-one really wants to continue using it. Of course this is easier said than done. But nevertheless countries will try and succeed at least to a degree to use non-usa systems.

Nevertheless USA is an impressive powerhouse, but part of that power comes from the whole world relying on U.S. systems. Which will change for sure.
