War and peace .

Srimad Bhagavatam 7.1.8 explains the turbulence of the material world, the modes of passion , goodness, and ignorance competing with each other for dominance both personally and with the greater communities both nationally and internationally and as well universally.

The Supreme Personality of Godhead allows the degrees of free will and determinism to take place,  naturally at different times either goodness,  passion or ignorance dominates. The Lord is impartial and  facilities the conditioned souls in their desires. Divinity sends endless representatives and brings forth theologically based cultures that brings the prominence of goodness , but its the nature of the independent self seeking enjoyers to abandon the good and take to passion and greed and envy and with such consciousness bring miseries to others . Wars and conflicts are also sometimes prominent when goodness is overshadowed. Eventually, darkness and ignorance set into humanity, and the good is forgotten and cancelled out almost entirely. These cyclic movements of the good , the bad, and the ugly constantly move in the millions of year cycles . Although everyone is facilitated , whatever the consciousness,  ultimately goodness  is again established by Divinity,  who reestablishes the principle of Goodness and a philosophically based science of self realisation,  that pushes ignorance and pride to one side .

One can read the words of Srila AC Bhavtivedanta Swami Prabhupada as he gives the full understanding of the text in hand .
