Anti-Vietnam War.

 War.

 The Vietnam War was a long, costly and divisive conflict that pitted the communist government of North Vietnam against South Vietnam and its principal ally, the United States. The conflict was intensified by the ongoing Cold War between the United States and the Soviet Union.  

Vietnam War song

War, huh, yeah
What is it good for
Absolutely nothing
War, huh, yeah
What is it good for
Absolutely nothing
Say it again, why'all

War, huh, good god
What is it good for
Absolutely nothing, listen to me

Oh, war, I despise
'Cause it means destruction of innocent lives

War means tears to thousands of mothers eyes
When their sons go to fight
And lose their lives

I said, war, huh good god, why'all
What is it good for
Absolutely nothing say it again

War, whoa, lord
What is it good for
Absolutely nothing, listen to me

it ain't nothing but a heart-breaker
(War) friend only to the undertaker
Oh, war it's an enemy to all mankind
The point of war blows my mind
War has caused unrest
Within the younger generation
Induction then destruction
Who wants to die, ah, war-huh, good god why'all
What is it good for
Absolutely nothing
Say it, say it, say it
War, huh
What is it good for
Absolutely nothing listen to me

it ain't nothing but a heart breaker
(War) it's got one friend that's the undertaker
Oh, war, has shattered many a young mans dreams
Made him disabled, bitter and mean
Life is much to short and precious
To spend fighting wars these days
War can't give life
It can only take it away

Oh, war, huh good god why'all
What is it good for
Absolutely nothing say it again

whoa, lord
What is it good for
Absolutely nothing listen to me

it ain't nothing but a heart breaker
(War) friend only to the undertaker
Peace, love, and understanding
Tell me, is there no place for them today
They say we must fight to keep our freedom
But lord knows there's got to be a better way

Oh, war, huh good god why'all
What is it good for you tell me
Say it, say it, say it, say it

huh good god why'all
What is it good for
Stand up and shout it nothing.

The song explains that war is not a right thing to do and that there's nothing good about war. Because a lot of lives will be taken and people will lose a lot of their loved ones. So that's why war should stop.
