War as a science, no, I would rather call it an art, since there is so much creative content, it has often taken commanders by surprise. This is the charm of war. I would often associate war with comprehensive mathematics, because a slight detail may lead to total loss. Of course, we as humans would spend our most sincere efforts to seek peace and avoid war. But once the effort proves futile, and the enemy threaten us with weapons, it is clear what we need to do - Protect our country, with our lives.
