The False Promise of Walls

I've spent half a century writing for radio and print (mostly print). I hope to still be tapping the keys as I take my last breath.

Former U.S. President Donald Trump was so deeply invested politically in building a wall on the border with Mexico that he seemed willing to risk everything to get it done. If history is a guide, and it usually is, building walls to keep unwanted people out doesn’t work.

Walls Have Ends

Pretty much the oldest civilization in recorded history was that of Sumer. Sited in the Tigris-Euphrates River valleys, it dates from about 4500 BCE.

For a couple of thousand years the Sumerian civilization jogged along but ran into troubles with a bothersome bunch of nomadic tribesmen called the Amorites. So, it was decided to build a wall to keep the nuisances out. The wall is thought to have been about 100 miles long but it only worked for a few years. reports that “Hostile invaders either penetrated the wall or simply walked around it . . . After the destruction of the city of Ur around 2000 BCE, Sumerian culture began to vanish from history.”

The Maginot Line

The same fate befell the Maginot Line four and a half thousand years later. This was a 300-mile concrete and steel defensive line of gun emplacements that ran along the border between France and Germany. It was supposed to be an impregnable fortress stretching to the North Sea that would stop Germany from invading France as it had done in 1914. However, along the border with Belgium the fortifications were much weaker.

Months into the Second World War, Germany simply drove its tanks around the lightly defended eastern end of the Maginot Line and occupied France.

The Great Wall of China

The world’s biggest man-made structure of its time, the Great Wall of China stretched eastwards for 13,000 miles from the border with North Korea. Construction took about 1,000 years, although it was not a continuous wall; there were stretches of earthen and wooden barricades.

The purpose of the wall was to stop pesky Mongolians from the north from plundering the high-quality textiles, food supplies, and other goods that China had. But, the barriers didn’t stop the raids.

Although numerically vastly outnumbered by the Chinese, the Mongols rode nimble horses and were very skilled with bows and arrows. The defences didn’t seem to deter them much as noted by National Geographic: “Instead of ceasing their attacks, the northerners learned that not only could their incursions gain them quick access to goods, but they could also be used as a threat to request even more aid from the Chinese.”

As history professor Pamela Kyle Crossley notes in Foreign Policy magazine, the Great Wall of China “did not amount to much in the way of security, but it certainly created an interesting obstacle course for anybody invading from the north.”

In the 13th century, Genghis Khan crossed the Great Wall and occupied the Chinese capital. His grandson, Kublai Khan, even established a new dynasty over all of China. That didn’t last long but the border skirmishes continued.

Eventually, in the 16th century, the Chinese gave up seeing the wall as a security asset and turned it into a customs and trading facility. However, over the next couple of hundred years massive stone and brick walls were built and those are mostly what we see today.

University of Pennsylvania historian Arthur Waldron is the author of The Great Wall of China: From History to Myth. He is quoted by Mother Jones as saying the structure “didn’t do what it was supposed to do, it was enormously costly, and there’s no question that it caused great suffering among the people who built it.”

The Berlin Wall

More recently, the poohbahs running the Soviet Union ordered the building of a wall separating East and West Berlin. The official reason for building the wall in 1961 was to keep Western fascists from infiltrating the Communist paradise in the East. The real reason was to stop civilians from leaving East Germany for what they believed was a better life in the West.

In addition to the 12-foot-high concrete barrier, there was barbed wire, a minefield, spike belts, and vicious attack dogs to deter people unhappy about life in the Utopian wonderland that was East Germany.

Nevertheless, brave and desperate citizens tried to scale the wall and about 100 were killed by border guards. Others successfully tunnelled under the concrete or flew over it in ultra-light aircraft or homemade hot-air balloons.

The wall was a dismal failure and became an ugly symbol of the dark repression practiced by Communist governments all over Eastern Europe. As these governments began to collapse in 1989, the citizens of West Berlin began joyously smashing the wall with hammers and chisels.

The Communist leaders learned what history could have told them: Walls don't do a very good job of keeping people in or out.

“Building walls between nations is an utter failure of the geopolitical imagination . . . Walls are a blunt instrument of diplomacy. At best, they offer temporary respite from deeper tensions which usually remain unresolved by separation.

Bonus Factoids

  • There are estimates that the building of the Great Wall of China cost the lives of 400,000 people giving it the ghoulish nickname of “the longest cemetery on Earth.”
  • According to The Economist, “Inmates at Oakwood prison in Staffordshire say drugs are easier to obtain than soap.” It is, it seems, not a problem to acquire drugs inside all prisons no matter how high the walls surrounding them.
  • In 1653, Dutch settlers built a wall across the width of an island they called New Amsterdam. They did so to keep out anticipated invaders and pirates. The wall didn’t work and, in 1664, four British frigates sailed into the New Amsterdam harbour and took over the Dutch colony, renaming it New York. The British dismantled the wall and the street that followed the line of the barrier became known as Wall Street.
