The more answers you have about the war, the better.

The outbreak of modern wars is no longer like in the past, and there is not necessarily a major conflict of interest, and the so-called just and unjust nature of wars is no longer so clear. Reproduce that under the framework of the United Nations, all countries have their own communication platforms for interests, and they are not too antagonistic to each other, thus weakening the risk of the outbreak of world war. Therefore, after the end of the cold war, the outbreak of the war showed a new development trend.

At present, such factors as terrorism, the struggle for geographical advantages, the expansion of strategic space, the interference of human rights and internal affairs, the expansion of contradictions among the people, etc., may all trigger wars, and the scale of wars is basically limited to local wars at present. As the world is multipolar, local wars plus diplomatic and economic comprehensive means have become a common practice to resolve differences in political interests. Therefore, the outbreak of modern wars will occur in all aspects, and what is important is how to solve them better. Satisfy the interests of all parties, not just solve the problem by war.

In a word, no matter how the times change and the political structure changes, under irreconcilable circumstances, the only extreme solution to political interests is war. clausewitz clearly pointed out at the beginning of On War that war is a means to obtain interests by violence.
