That's hilarious you assume they meant 100 years from now
No matter what underhanded intrigue any major power on the planet does today, those methods will never be able to eliminate a nuclear armed peer.
In the case of the US empire, there is nothing that China or any other country can do to conventionally defeat it. The only way for a nuclear armed power to fall and/or balkanize is from within due its own internal economic, political, cultural, social, racial, etc. weaknesses. Hence, if the US empire is going to collapse, as I and many other scholars believe, it will do so primarily for those domestic reasons rather than geopolitical ones.
Those in the US empire who are constantly putting the blame of its domestic troubles on Russia, China, Iran, etc. are doing nothing but a disservice as it only hides the rulers of the US empire from accountability, who are the ones truly responsible for America's problems.
