Ethnic Armenian refugees crowd a road as they flee Nagorno-Karabakh in September 2023, carrying belongings and children.

By late September 2023, the ethnic Armenian population of Nagorno-Karabakh had effectively ceased to exist as a community. Some 100,400 people fled. That is 99% of everyone who lived there. They left behind a couple of dozen individuals. The rest were gone in days.

This did not happen overnight. The groundwork was laid over years. The region, internationally recognized as part of Azerbaijan, had been governed by ethnic Armenians since the first war in the 1990s. That arrangement held for three decades. Then came the Second Nagorno-Karabakh War in 2020. Azerbaijan took back large swaths of territory. The population of the self-declared Republic of Artsakh shrank. Those who stayed were already diminished, already vulnerable.

After that war, the blockade began. For nine months, Nagorno-Karabakh was cut off. Supplies dwindled. People struggled to survive. The report from the region described a dire situation. Threats of ethnic cleansing were made openly by Azerbaijan. The blockade was not a natural disaster. It was a political act, sustained over time, squeezing the population.

Then came the military offensive. It started on September 19, 2023. The self-declared republic surrendered. Its armed forces disbanded. The mass displacement followed immediately.

The human cost is not abstract. It is measured in bodies. While fleeing to Armenia, 288 civilians died. The single largest cause was an explosion at a fuel distribution center. That killed 218 people. Another 70 died on the road, somewhere between their homes and the border. These are not battle casualties. These are deaths that occurred during a flight for safety.

Azerbaijan had issued public assurances. The Armenian population, they said, would be protected. Those promises now ring hollow. The evidence of what actually happened contradicts them. The entire population is gone. Protection was not provided. The result is the same as if it had been the stated goal all along.

International observers have used strong language. Many experts describe the forced displacement as a war crime. Some call it a crime against humanity. The distinction matters in legal terms, but the underlying fact is the same: a population was driven from its homeland by military force and prolonged siege.

The United States is being watched closely. As a key player in global affairs, it has a responsibility to condemn such abuses. The sitting president has an opportunity to demonstrate leadership. So far, the response has been measured. The international community is demanding answers. Whether those answers lead to action remains unclear.

This is not a new pattern. It is an old one, repeated in different places at different times. A disputed territory. An ethnic group in the wrong place at the wrong time. A military advantage pressed to its final conclusion. The rest of the world watches, issues statements, and moves on. The people who fled are now refugees in Armenia. They are alive. They left everything else behind.
