of course, the best thing to do would be to sit down with everybody and say "look, there have been injustices committed to all of you, i'm sure of that. however, look at what you're doing. you're wasting your lives trying to destroy other people. you could be happy, but you're not. think about if you had taken all the energy used to plot and destory, and put it towards something that's productive. there's no doubt that you would have a strong economy, and a high standard of living. so please, lets all put down the guns and bombs, and think about what really matters in this world. there have been injustices committed, but to dwell on them is only going to hurt yourself even more."
but i doubt anybody would listen.
