The enemy is he who shakes the jar

This is a jar of ants.

If you put 100 black ants and 100 red ants in a jar, nothing happens. But if you shake the jar violently, the ants start killing each other. The red ants consider the black ants their enemies, and the black ants consider the red ants their enemies. The true enemy is the one shaking the jar. The same thing happens in human societies. The lesson is - before we attack each other, we should think about who is shaking the jar!
