Certainly, there is the possibility that politics will become unstable by changing the leader each time by the election. Even if it is thought that a strong leader in the election is necessary, democracy should be required to cooperate with citizens of various positions.
Thus, strong leadership like a dictator should not be necessary.
Conversely, since many countries try to maximize their benefits in international relations, there is a possibility that they will lose pace in international politics if they are not strong leaders.
Therefore, strong leaders are required in externally, but sometimes qualities that can cooperate are required.
