looks there is immeadiate war. first, china was once defeated badly by Japan, they want revenge.maybe just use this as an excuse. second, china may want to change its standing, may want to chanllege the already defined rules, particulay u.s. leadership, they think they are powerful enough, and they start to think they can lead. being a second means listen to others, no one likes this. if that happens, as japan ally, U.S. may join. then Russia has issue in island with Japan too, Russia may join China to take advantge of this sitaution... the war may become bigger, bigger... if the war happens, what will hit hardest? weapon factory may benefit the most?
