求 bob dylan 的 Masters of War的歌词及背景！！万分感谢！：-）

歌词如下:
Come you masters of war
You that build all the guns
You that build the death planes
You that build the big bombs
You that hide behind walls
You that hide behind desks
I just want you to know
I can see through your masks

You that never done nothin'
But build to destroy
You play with my world
Like it's your little toy
You put a gun in my hand
And you hide from my eyes
And you turn and run farther
When the fast bullets fly

Like Judas of old
You lie and deceive
A world war can be won
You want me to believe
But I see through your eyes
And I see through your brain
Like I see through the water
That runs down my drain

You fasten the triggers
For the others to fire
Then you set back and watch
When the death count gets higher
You hide in your mansion
As young people's blood
Flows out of their bodies
