Why is war always an option?

It's the way to know who is brave and strong. Humans is always like that and I think with the world today, it's hard to remove the minds of the people about getting war.

we humans tend to wage war over misunderstandings that can just be settled in a non violence act. But then when we come to think of it, if there is no war, people too wouldn't listen. They just tend to pretend that nothing is wrong. But i do hope the war would end soon, because it is just going nowhere.
