I'm scared of war
What else are you scared of?
I'm scared of my own personality. I start to hate people very quickly.
Fear can interrupt processes in our brains that allow us to regulate emotions. If your fear of war is affecting your life, you should talk to someone about it so that you can get past it.
We should just strive to end wars.
I agree, and it is very unnecessary to lose lives just because of war and I feel like I am with you when you say that we should just end all wars but it is not a realistic goal, as we are humans and it is our history that we would constantly have conflicts no matter how small it is. What we can do in instead is to just elect people who are more peaceful and caring.
