Further, democratic negotiators, or foreign negotiation specialists accepted to assist in the negotiations, may in a single stroke provide the dictators with the domestic and international legitimacy that they had been previously denied because of their seizure of the state, human rights violations, and brutalities. Without that desperately needed legitimacy, the dictators cannot continue to rule indefinitely.

Nonviolent action involves opposing the opponent's power, including his police and military capacity, not with the weapons chosen by him but by quite different means. Repression by the opponent is used against his own power position in a kind of political "ju-jitsu" and the very sources of his power thus reduced or removed, with the result that his political and military position is seriously weakened or destroyed.
