The course is not centered on the American perspective. I appreciated learning about the dawn of the women's movement that started first in New Zealand and gradually spread around the world.

Do leaders have the will to kill their own people? The leaders of the Soviet coup attempt against Gorbachev did not. The Chinese leaders did.
