The Myanmar military’s disinformation was crude but effective.

Army propagandists claimed an ethnic group called the Rohingya was burning down its own villages and wanted to swamp Buddhist-majority Myanmar with Islamic hordes. The Rohingya were spinning tall tales, the military said in 2017, about soldiers committing mass rape and murder.

The truth — that troops were waging genocidal operations against Myanmar’s ethnic minorities — was perhaps too shocking for some members of the country’s Bamar ethnic majority to contemplate.
