Hmm, is that why the USA has been declining in relative power every single year since 1991?
And not just compared to China, but compared to the rest of the world. The only way to stop this trend is for the rest of the world to suddenly stop developing themselves, and that isn't going to happen.
Every year that passes, America's relative power continues to decline. The best you can hope for is that you won't have to see it decline much further than it already has, as shown by incidents such as Scarborough Shoal 2012 or Crimea 2014. Even smaller countries like Iran and North Korea are openly challenging the USA and succeeding, Iran got to keep their nuclear program (with Obama's blessing), and NK is developing thermonuclear weapons along with the ballistic missiles needed to carry them to American shores.
America in 1991 wouldn't have allowed any of these things to happen, but now they are powerless to stop it.
Ignore our friend @gambit as he once said that the US economy will forever be the most dominant in the world.
He may know a little about military matters but needs to stay away from economics and politics as those are obviously not his areas of expertise.
