You’re Bad at Preventing What You’re Good at

Some four thousand years ago,
One of the rulers of Ur

Tried to keep the Amorites
Away by building a wall.

It didn’t work. Amorites
Were already all over.

Babylon was full of them.
History has forgotten

The ruler who built the wall,
Remembered Hammurabi,

One of the Amorite kings.
It’s hard to keep humans out

Of other humans’ homelands.
It’s an invasive species,

Restless, pervasive, shifting,
Populations frequently

Replacing populations.
It’s odd people even try

To keep other people out
Raising so many failed walls.
