The world today is not peaceful, and local conflicts still exist ... How do we view war?

In addition to affection and other feelings between people, it is interest. And interests are either the opposite of interests or the same side of interests. If the former is much higher than the latter, there will be conflicts. When the two sides of the conflict are big enough, such as reaching the national level, there will be war. War is the last resort to resolve conflicts of interest, but it is a double-edged sword. Regardless of success or failure, both sides are losers in the end. The difference is that winners can get more benefits from losers to make up for their losses. So try to avoid war.
