When was the designation of Vietnam Conflict changed to Vietnam War?

Answer 1

Means the same thing. Officially the American Civil War was not a war according to those that believe only "a declared war" is a real war. Since the US Civil War was not a "declared war", its officially designated as the "War of the Rebellion" and/or "the war between the states."

By this definition, no wars have been fought since WWII; America's last declared war. And don't forget, the US Civil War wasn't a war either! (According to those "not a declared war" people).

To answer your question, the Vietnam War has always been called both, even during the 1960s.

Answer 2

To date, there have been no US declared wars in the atomic age. The last declared war was WW2; before the atom bomb was invented.

Answer 3

No
