Is China Really the Most Powerful in the World?

I think for the past, you know, century, it was all almost natural for people to think that the US is at the top of the world. I don't understand how this ludicrous like concept seems to be proliferating. China's doing amazing things for its own people and hasn't been involved in a military conflict with another nation in decades... We need to stop this cycle now. It's an echo chamber where some media organizations or leaders are saying it and then others are echoing the same gobbledygook which makes no sense in reality.
