For example: 1, Korean War, American invasion of Korea, his injustice, Korean people and China people.

Just for the people's volunteers against America! !

2. The Kosovo war, NATO and the United States bombed Yugoslavia as aggression, and their resistance was.

Just!

3. In World War I, there was no justice between the allies, because the old imperialist countries represented by the allies and the emerging imperialist countries represented by the allies had great differences and irreconcilable contradictions in the distribution of global interests. Before the war, both sides prepared for the war and mobilized. Only Germany started first.

4. In the first Gulf War and the second Gulf War, Iraq lost in both wars, but Iraq was an unjust party in the first Gulf War, and the winner of the second Gulf War, the United States, established an unjust party.

5. China people's War of Resistance against Japanese Aggression, the war of liberation, these wars to resist aggression and overthrow tyranny should all be regarded as just wars.

A war waged for the benefit of a certain country or some countries, such as the Iraq war, is unjust.

But it should be difficult to distinguish, just like War of Resistance against Japanese Aggression, which is just from China and unjust from the invaders, that's all ~!
