7. The Vietnam War
The Vietnam War (1955-1975) was a protracted conflict that resulted in over 3 million deaths, including combatants and civilians. The war’s impact extended beyond Vietnam, significantly affecting neighboring countries (historyrise.com). In Cambodia, the U.S. bombing campaigns aimed at disrupting North Vietnamese supply lines inadvertently destabilized the country and contributed to the rise of the Khmer Rouge. (By 1975, the Khmer Rouge, led by Pol Pot, seized power and initiated a brutal regime marked by genocide and widespread suffering.
Laos, a neutral country during the conflict, became heavily bombed due to its proximity to Vietnam (brainly.com). The extensive bombing campaigns resulted in severe damage to infrastructure and lasting environmental impacts. The war also led to one of history’s largest refugee crises. An estimated two million civilians left the country after 1975, completely reshaping Southeast Asia’s demographics.
