I really hope we reach a point where war becomes unnecessary, I think if we all strive for peace it is achievable

Although this is something I hope for, I think the patriarchal nature of politics will prevent humanity from making any great strides to world peace. Too many self-absorbed, egotistical, narcissistic and violent men are running/ ruining the world. Politics in a boys club, and women are not supported in their career goals.
Look at Hillary / Trump - Hillary was the lesser of two evils, but Trump - the stupidest man on the planet - still won.
