Superpower
From Wikipedia, a free encyclopedia written in simple English for easy reading.
A superpower is a country that is one of very most powerful countries in the world. It is more powerful than a major power. The United States and the Soviet Union were the world's two superpowers between 1945 and 1991.
After the Soviet Union split into a lot of smaller countries in 1991, the United States was the only superpower left. Today, the United States is still the only superpower. China, India, and the European Union might be superpowers someday.
