America had a lot of power in the 1900s, the 20th century. But China is trying to take over the world in the 21st century. Why do you say America is bigger than China? Who told you that or is it based on a map you saw? Perhaps you saw the wrong map.

Dear Hive account@joeyarnoldvn, If you look at the current map of mainland China, you will agree with me. China forcibly annexed Tibet and Uyghurs to make it part of what is now China. If you look at the current map of mainland China, Tibet and Uyghurs are Chinese territories.
I believe that American rule is controlling the whole of the New World.
At least the direct U.S. powers govern all of North America.

I think the real power of the US governs all of North America. So, I said that the continent of North America, dominated by the power of American rule, is larger than that of China.
