Princip was an agent of the Serb Military, Perhaps you and Oliver Stone believe Oswald was an agent of the US government, but nobody else does.
I'm familiar with the story, and the Black Hand, etc. etc. They did not create or enforce the tangle of mutual defense treaties that was the real cause of WWI, nor did they ever represent the Serbian people as a whole.
To point at Serbia as determinant of world military and political policy is both simplistic and false.
Perhaps you and Oliver Stone believe Oswald was an agent of the US government, but nobody else does.
Your use of bogus strawmen serves only to discredit you. I hold no agreement with the ravings of Oliver Stone, nor with your puerile attempts to put me in a box with him.
If your opinions have merit, you need not resort to such pathetic and desperate measures to advance them.
