Define “external”?

External to the planet?

The hemisphere?

The continent?

The lands previously a part of a former empire?

The lands that a country lost to a war?

A country border drawn arbitrarily (straight!) by an English Lord hundreds of years ago?

A country border not everybody agrees about?

A country border defined to keep out intervention more than to protect?

A country border that is porous and is walked across daily by people that aren’t even sure where it is?

Etc…

At some point you may release that humans live on both sides of lines that often exist only on maps, and serve only to keep people servile to autocrats.

Autocrats whom make sure that their schools teach the importance of borders.
