What is it good for- Tapan Darji

There is a time for war. War is only just when one group or person won't listen to another. Examples of this are when a government isn't leading to their citizens or when another group is attacking another group. This can include the oppressed group fighting back or an outside group attacking the attackers.
Countries should only go to war when another country is threatening or attacking them and the two sides can't negotiate a treaty to prevent fighting. Or a country can go to war to support its allies if they are being attacked for an unjust reason. If their allies are the attackers the country shouldn't enter unless it is a just cause and  the allies are losing.
The only alternative to prevent war is through compromise. Compromises are mostly effective but only if the parties are willing to compromise. If the parties aren't willing to listen and compromise then war is inevitable.
