I think it's a pipe dream, I can't fathom ever achieving world peace. Everyone has different views and live life differently, some countries are extreme while others aren't. Wars will constantly exist because countries will constantly be against each other. You've got numerous dictators in countries like Russia who want the world to conform to their barbaric ways of living.
Just a dream. You can’t force people to along and it will never happen. Everyone has different opinions and many people will act differently towards an event/problem that happens. It is just how the world will always work and nothing will change that.
I don't think it's possible. It's a nice thing to imagine. In fact, John Lennon even wrote such a song. 😄. Anyway, I am cynical about the whole mess and realistic. Should I be that way?
