Why did Vietnam and Cambodia have a war?

Answer 1

The conflict between Vietnam and Cambodia, particularly during the late 1970s, stemmed from the Khmer Rouge regime's aggressive policies and border disputes. The Khmer Rouge, led by Pol Pot, sought to expand its territory and often attacked Vietnamese villages, leading to significant tensions. In response, Vietnam invaded Cambodia in late 1978, ultimately toppling the Khmer Rouge in 1979. This intervention was motivated by both humanitarian concerns and the desire to eliminate a regime that posed a direct threat to Vietnam's security.
