USA does what is best for USA. Each and every country in this world does exactly the same including using countries for their own benefits and then dump them, but why not if they no longer serve any interest. China is no different, for China, China comes first and will do the same if needed.
People wishing for the unraveling of American power or wishing for it's demise in future don't appreciate all the good things America has also done for the world and for most part kept the peace in the world as a global cop. In the backdrop of the recent chaos rampant in the United States, and in the light of America’s growing isolation in the international arena specially due to the policies of agent orange in the white house, we are hearing claims that the world is witnessing the decline of the United States as a superpower. For as long as I can remember, I have been hearing that the United States is done for, but in practice its influence has never been stronger.
Since the 1980s arguments about the American empire sinking and other forces in the world are rising have been voiced time and again. Just recall how after the 2008 economic crisis, the dire predictions were made about the rapid deterioration of the United States, but as it turned out, those prophets of doom were too quick to write off the resilience of American economy and the resilience of American people overall. Today, USA still ranks higher than the rest of the world in the global innovation ratings and America is still the leading political and cultural power in the world.
In the new cold war that is developing between China and America, there good reasons to be apprehensive about the domination of the Chinese political model which is a centralist dictatorship that aims to maintain a tight grip on the lives of the country’s citizens. But there are also good reasons to believe that the current Chinese model could change, as political trends in China have changed in the past.
