I can't really watch at all that war and making bombs through unproductive science. Its one thing to manipulate people and be a ruler, but sending thousands of people to death is very dumb. Why the presidents does not fight 1 vs 1 when there are international problems ? The solution is clearly simple, without setting families in danger and even landscapes, did you knew that war is a pollution of the environment ?? why do humans die because of personal problems of someone other. And with all the other solutions, we damage mother earth so badly that we all gone die(yes you can't live when there is no kind of tree).
