Lyric discussion by EternalTearsOfSorrow 

it was written about 'Agent Orange' a herbicide used by the US Military in Vietnam. It's about how they would fly overhead & spray the Agent Orange on the Vietnamese. Tons of people, mostly Vietnamese, got cancer, had horrendous birth defects, etc., some of those affected were US's own soldiers themselves as a result of the spraying. The "I've got my spine" is about a US soldier who appreciates that he still has his spine in tact (literally) but the lyrics are him remembering back to all the spraying & how wrong it was but he didn't realize at the time all the damage it would cause.
