In 1972, the city of Hanoi witnessed a pivotal moment in the Vietnam War, known as the "Dien Bien Phu victory in the air," during Operation Linebacker II. This event inspired the development of the game "Hanoi 12 Days and Nights" by Pirex Games, which focuses on the theme of revolution. The game aims to recreate the intense aerial conflict that took place over Hanoi, where the local population heroically resisted the massive air raids conducted by B-52 bombers of the US military. This confrontation, dubbed the "Dien Bien Phu in the air," showcased the resilience and determination of the Hanoi people against the formidable might of the US imperialists. By the end of December 1972, the pressure of this campaign led the US government to sign the Paris Agreement, paving the way for peace in North Vietnam.
From the perspective of the United States, Operation Linebacker II, also known as the "Dien Bien Phu in the air" campaign, marked the final military operation against the Democratic Republic of Vietnam during the Vietnam War. This operation took place between December 18 and December 30, 1972, following the breakdown and collapse of the Paris Conference due to unresolved disagreements between the Democratic Republic of Vietnam and the US regarding the terms of the peace agreement.
