The correct answer is: "Saigon"
The war in Vietnam took place between 1955 and 1975. The country had splitted in two confronted halves. North Vietnam was supported by the URSS, China and other countries of communist influence, while South Vietnam established its capital in Saigon and was supported by the US, South Korea, Australia and other anti-communist allied countries. Therefore, this national conflict became a proxy war in the larger conflict known as Cold War, between the Eastern bloc constituted by the URSS and its allied countries and the Western bloc leaded by the US and integrated by other anti-communist countries under its influence.
