What’s in my Big question for me

My big questions is a question that comes from both my mom and I . We both always talk about the issues going on between countries or just in our own country. Then she starts going on about how none of it’s necessary, but is it? Like war what’s the point of it? Often we keep talking about and there always is a reason for it, such as issues with politics or an invasion sparking up. But I mainly always come to the conclusion to ask my self why? But finding an answer would make me understand why it happens and why it’s necessary.
