Lyric discussion by MickMusic 

No, it isn't about Vietnam (although it is about war). PaliSteve is right, it's about nuclear war. This was written during a long cold war where everyone was afraid someone would accidently "press the button" and trigger "mutually assured destruction". It was during the time of the movie 'War Games'. I imagine even Austrailians were worried about it.

Jump down the [fallout] shelters... No surface noise now [everything is dead]... we know that you love all that power... It's a mistake [oops I thought you attacked so I pressed the button]...

It all refers to nuclear holocaust.

MickMusic is the closest. Given the era when this song was released (1983) Ronnie (Ronald Regan) was President and challenging the Soviet Union making many think he would bring us to war.
