1. In the modern history of the world, revolution has changed the nature of society. Only countries with strong feudal forces use reform and transition, such as Japan, Germany, South Korea and Italy.

Germany and Italy mainly carry out transitional social nature in the form of national unity, which should be classified as reform.

There are obstacles in the future modern government, such as Japan's imperial autocracy and militarism, which hide the source of war.
