War as a process of change works successfully. That is why people are so dependent on it. It is much easier to break someone's spirit with brute force than to use intellect and reason. War as a transformation process will continue unless people see that the same evolutionary processes of change in society can be implemented through negotiation. But these types of processes are slow and involve a willingness to be open to change.
People have to get the idea in their head that change is inevitable, it is what life is based on.
The status quo can not remain forever. It is only through this realization and openness to new ideas that war as a machine of progress can ever be stopped . Skilled leaders need to motivate people to negotiation, and to acting without aggression. To lose the 'us against them mentality' should be the ultimate goal of all societies and peoples. Every day should be Christmas.
