War is a state of armed conflict between politically motivated groups. War is caused as a result of the ultimate evil; that is, people wanting to ignore people’s freedom by dominate them for their own ends.
Does God want war?
No:- If everyone followed his ways then there would be no war,
Yes:- When evil gains an upper hand then good has to fight against it.

Jesus taught us to love our enemies but we have to hate evil and stand up against it and that means judging when something is evil and fighting it. Consider the plight of the Jews in Egypt when they were abused as slaves, first with no fighting God had Moses ask for they release several times, when ignored he caused the deaths of the first born of Egypt and eventually the destruction of the Egyptian army and so release his people into freedom.

When is War Justified?
• The war must be for a just cause and only waged as a last resort, all other ways of resolving the problem should have been tried first.
• The war must be lawfully declared by a legitimate and lawful authority.
• The intention behind the war must be good, such as self-defence.
• Innocent people and non-combatants should not be harmed.
