Second Cambodian-Vietnamese War

"''"After Saigon (now Ho Chi Minh City), nothin's gonna be the same. But we finally got a foothold into Cambodia. The gateway to the Khmer Rouge-occupied lands is open and there's no turnin' back. For any of us. It's the Second Cambodian-Vietnamese War. By now, it looks like we're approaching our hopes and dreams to liberate this place right now.''"

--Su Ji-Hoon, Death Factories

The Second Cambodian-Vietnamese War was an armed conflict between the Socialist Republic of Vietnam (lead by Lucy Loud after Liberation of Saigon) and Democratic Kampuchea (controlled by Khmer Rouge and lead by Pol Pot) after Cambodian–Vietnamese War.

Only happened after Liberation of Saigon and in during Third Beacon War from Rubyism Conflict that the Khmer Rouge attacked South Vietnamese locations of Vietnam due to revenge that caused Vietnam strike back and counterattack.
