do you think your invading neighbors will share your philosophy?
Exactly. War has always been around and has always been an effective method to preserve interests. Is it the best method? Most certainly not. Does it give way to a mass of other problems? Certainly. Since the birth of civilization, people have lived by the sword. I guess its an act of desparation, either an inability to plan a better method or a fear that there isn't one and either party is going to be crushed if they don't act. Act or react if you will because people will always feel entitlement towards something.
