Getting caught up in that "political debate" are you? If you're talking about that piece of paper called a "declaration of war", then there hasn't been "technically a war" since 1945. Because WWII was America's last declared war.
Also, if you still want to discuss that "piece of paper" (a declaration of war), then the US Civil War (American Civil War 1861-1865) was NOT A WAR either. It didn't have that "piece of paper" either.

No.
The dictionary defines two (or more) recognized nations fighting each other as a war. A battle is one engagement or series of engagements over the same objective (a hilltop or city for example). And technically the American Civil War is considered the "War of the Rebellion" in the US Government archives. Neither the US Civil War nor the Vietnam War were declared wars.
North Vietnam/VC vs allies
Vietnam and Cambodia
It was fighting for democracy and against communism.
The same way the US Civil War (American Civil War) wasn't technically a war. Neither were declared.
