I know it's been a while, but I was recently looking for chords for The Internationale and came across the version by The New Singers from the "Songs For Political Action" CD and tried my hand at figurng them out. I think I got pretty close but could use a tweak or two if anyone out there would lend a hand.
(I hope the line spacing lines up correctly.)
Here they is:

   G                                 C
A-rise ye prisoners of sal-vation,

    D                                 G
A-rise ye wretched of the earth,

      G                                  C
For justice thunders condem-nation

    D                      G
A better world's at birth

      D                                       D7
No more traditions chains shall bind us

             A7                   D
Arise ye slaves, no more enthrall

       D                                     G
The earth shall rise on new foundations

                      A7                        D
We have been naught, we shall be all.


(Chorus):
            G      C
'Tis the final conflict,
             D                G - D7
let each stand in his place

       G                C
The International Soviet

       A                   D
Shall be the human race
            G      C
'Tis the final conflict,
             D                G - D7
let each stand in his place

       G                C
The Internationale Soviet

       G       D          G
Shall be the human race
