This Diaoyu island spat is a private matter between China and Japan even if it escalates into military confrontation rightfully both sides should take the position that they will not involve outsiders including the US.
If a particular Japanese Government can win votes on militarism with whatever excuses, then it only demonstrates that their Imperial Militarism dream since WWII is still very much alive today even amongst the common people there.
What is more when Japan speaks about prostitution as a necessity a recent fracas, it is another evidence that nation hasn't change at all since WWII.
Japan may introduce many seemingly peaceful institutions, but all these seem like superficial acts designed to camouflage genuine inner-ambitions only. No women in US stood up at all against the Japanese when they spoke favorably on prostitution. That statement came out from a learned leader, not a street slump idiot! Had that statement came out from China, Hilary C. may have led a legion of women and dive into China with nuclear standard of media bombardment internationally. So where are the US women? US if it wants to win international minds must abandon Japan. It is stupid for US to win Japan no matter how US shapes her and lose the entire world. Every Asian knows today's Japan is the works of US. So why should US shape Japan?
