Wasn't there a song about war and bombs:

Don't you hear the H-bombs' thunder
Echo like the crack of doom
when the skies are wrent asunder
fallout makes the earth a tomb

had a part in it about bringing death to a stranger

murder folks in distant lands
would you bring death to a stranger
have his blood upon your hands?

I can't remember much more of it as I am just a hillbilly (and a young one at that) but i thought I recalled that and it sounded appropriate for these times.
