Hyperpower

A hyperpower is a country that is more powerful than every other country in every aspect. It is more powerful than a superpower.
The United States was considered (but doesn't seem to match the qualities of a previous named hyperpower). The US was thought to be a hyperpower by some after the Cold War because it was the only superpower after the collapse of the Soviet Union but people still argue that the United Kingdom is the only country ever to be a hyperpower due to the size of it's Empire (the biggest in history). People also believe the United States of America has had a big influence in politics, science, culture and military. It also influenced the balance of power and made a new world order.
Some say that the United States is still a hyperpower because it is the only uncontested superpower (some say that China is/will be a superpower and some say it is/will not). 
According to the Asia Power Index 2020, the United States still has the lead on the "military capacity", "cultural influence, resilience" and "defense networks," but falls behind China in "economic and future resources", "economic relationships" and "diplomatic influence". This index ranks power and influence only in Asia Pacific.
It is easy to see areas where the United States is no longer so dominant. Its economy is weakened by manufacturing abroad; internal social conflicts are greater. However, it is still by far the top country on military capability, though not on size of its army. Perhaps the world no longer has a hyperpower.
