I was taught in high school that during the Cold War, there were maps with the US centered and USSR divided on either side to imply American unity in the face of opposition.

The maps were common, but there was nothing anti-USSR about them, and they go way back before the Cold War.

It's long been practice for maps to be centered on the country/continent they're produced in. American world maps centered on the Americas, British world maps centered on Greenwich, Chinese world maps centered on East Asia.

These days we've mostly standardized on the more "neutral" choice of having the edges in the middle of the Pacific because that minimizes the land getting split up, but there are also Asian maps that split in the middle of the Atlantic, since Greenland's population is low.

In China, world maps have China more centered with America to the right. Some pics I took recently: https://gist.github.com/olalonde/d293e54c46143c3dd905da4c0eb...
