I'm speaking to the last several hundred years including colonial times, early 1800s, post Civil War, early and late 20th century and the present. The number one economy in the world for over a century and counting.

Even in recent times, the U.S. has out-paced the EU. The U.S. economy is now 50 percent larger than the EU. There was a lot of talk of China surpassing the U.S. as recent as 8 years ago, however, the U.S. has pulled out ahead as China's growth has stalled. And the USSR no longer exists, but to the extent that you can equate it to Russia, well the Russian GDP is smaller than some individual U.S. states.
