The United States does not control Canada. North America consists of Canada, Mexico, and the USA. In other words, North America has three countries.

USA may have influence over the world. USA has military all over the world which is a form of power perhaps. Globalists and other groups of people may control or try to control many countries. Some of those people may live in America and other countries. So, we should assume some of the control freak globalists are bad or at least do bad things. So, perhaps some of these bad people get into U.S. government to do bad things. Perhaps they work with other people who then work with some other people who then work with different groups in different countries. So, many things may be happening. So, it might be said that globalists or Deep-State or the United Nations or central bankers or other groups do try to control and take over the world. But the USA itself was not created back in the year 1776 to control the world. Maybe the USA can influence the New World and China too. People in China copy USA products, services, ideas, culture. So, the USA influences the world but is not supposed to control or rule the world. But some people try to rule and control the world. Some of the bad people who try to control the world might be Americans. But that is not America. That is not what America is supposed to be all about originally with the Founding Fathers, people like George Washington didn't want the United States to become the United Empire of the Entire Earth. The USA is cooler than Canada. But Canada is not a slave to the USA.

The USA has free speech in their constitution found in the first amendment which says American citizens have free speech. Canada and most countries around the world do not have free speech. If you say something like Hate Speech for example in Canada, police will come find you and take you. Now, bad people are taking over the USA too. So, good people have to save the USA before it is too late.

The U.S. is 3,794,083 square miles according to Reference.com.

China is 3,696,000 square miles according to Reference.com. So, that means you're right, U.S. consists of more square miles than China by almost 100,000 miles, apparently.

Wikipedia said China is 3,705,410 square miles. It says 2.8 percent of that is water.

Wikipedia said the U.S. is 3,531,905 square miles if you only include the land and not the rivers, lakes, seas, water. It says U.S. is 4.66 percent water. So, according to Wikipedia, China has more land mass than the USA.

It looks like China has 2.8% water and America has 4.66% water. So, if you include water and land together, then I think the United States might be bigger.

Russia is 6,612,073 square miles total of only the land or maybe of the water and land together. It says 13% of it is water.

Australia is 2,969,907 square miles. It has 1.79% water.

Canada is 3,855,100 square miles and is 11.76% water.
