The Human Cost of War

Thong Phet was an 18-year-old novice monk when the swing of a machete altered his life irrevocably. The blade came down on an unexploded weapon that he had not noticed, detonating the device. As he watched a team from the Lao National Unexploded Ordnance Program methodically work across one of his pastures on the outskirts of the village of Ban Napia in northeastern Laos, Phet recalled the accident: "A friend took me to the hospital. I was conscious the whole time. They had to amputate my left arm below the elbow and my right hand was badly injured as well," he told DW.

Phet's injury is one of countless tragedies linked to the legacy of the Vietnam War. Though Laos was not officially involved in the conflict, the Ho Chi Minh trail ran through its eastern provinces, and Xiangkhouang Province was a stronghold of the communist Pathet Lao movement. From 1964 to 1973, the United States dropped more than 2 million tons of explosive ordnance on Laos, making it the most heavily bombed country per capita worldwide. Weapons ranged from incendiary rounds to rockets and 2,000-pound (907-kilogram) bombs, but the device that caused — and continues to cause — the most fear is the cluster bomb.

The Cluster Bomb Threat

Cluster bombs are designed to break apart in midair, releasing up to 600 bomblets, each smaller than a fist, contaminating an area the size of several football fields. An estimated 270 million of these sub-munitions — known locally as "bombies" — were dropped on Laos, and about 30% failed to detonate. Many remain where they fell half a century ago, a persistent threat. Phet remembers the bombings vividly: "I remember seeing aircraft coming and hiding in caves near here with my parents when I was a boy."

The village of Ban Napia has lost five people to unexploded ordnance (UXO), and a significant portion of its land is contaminated. Previous search efforts have unearthed over 6,000 individual bombies. The demining work is painstaking and slow; in one recent week, a seven-strong team from UXO Lao made safe 19 bombies and five large-caliber bullets.

Key Claims

  • US bombing of Laos (1964-1973): More than 2 million tons of ordnance were dropped, making Laos the most heavily bombed country per capita.
  • Cluster bomb contamination: An estimated 270 million bomblets were dropped; about 30% failed to detonate immediately, leaving a lasting danger.
  • Local impact: Ban Napia has recorded five deaths from UXO, and over 6,000 bombies have been previously found in the area.
  • Demining progress: A UXO Lao team of seven cleared 19 bombies and five large-caliber bullets in a single week.
  • Development obstacle: UXOs make everything more costly and slower, hindering development; over 70% of the rural population relies on agriculture and natural resources.
  • Treaty status: The Convention on Cluster Munitions has been ratified by 112 nations, but not by the United States, Russia, or China. Signatories are obligated to never use, develop, produce, or stockpile cluster munitions.

A Path Forward

Despite the scale of the problem, efforts to mitigate the threat are showing results. Demining operations and education campaigns have reduced casualty figures: from 44 incidents and nine fatalities in 2015, to 33 incidents and seven deaths in 2020, and six deaths in 25 detonations in 2025.

Laos has adopted an 18th Sustainable Development Goal focused on making lives safe from unexploded ordnance, a unique national commitment. In September, Laos will host the Third Review Conference of the Convention on Cluster Munitions, bringing together nations that have pledged to eliminate these weapons.
