In the decade during which you claim China has been preparing for a hot war, the United States invaded multiple countries and waged hot wars on three continents.
It’s ridiculous to compare China to the US when it comes to warmongering. They’re not even in the same ballpark.
Yeah, the US is not an incredible actor, but China is funding the most brutal war in modern history (the invasion of Ukraine) in order to provide a smokescreen for their own invasion.
The Ukraine war is large and terrible, but its nowhere near comparable in brutality to the genocide in Gaza, that the US is funding, providing weapons for, and protecting diplomatically.
