Dictatorships usually exist primarily because of the internal power distribution in the home country. The population and society are too weak to cause the dictatorship serious problems, wealth and power are concentrated in too few hands. Although dictatorships may benefit from or be somewhat weakened by international actions, their continuation is dependent primarily on internal factors.

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.

By placing confidence in violent means, one has chosen the very type of struggle with which the oppressors nearly always have superiority.

Dictatorships are never as strong as they think they are, and people are never as weak as they think they are.

The degree of liberty or tyranny in any government is, it follows, in large degree a reflection of the relative determination of the subjects to be free and their willingness and ability to resist efforts to enslave them.

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.

It's a nonsense assumption that you can get rid of terrorism with war. Terrorism is taking the lives of innocent people to gain your objective. War is basically the same thing on a larger scale.
