Let me explain to you why you are silly and not fully think through your argument.

1. If these Japs response by attacking China because, China fire missiles and shells into an empty island; what do you think the over ramping response from Chinese army and the Chinese citizen will be?  This is a declaration of War from Japan, for an UNPROVOKED response, making Japan an aggressor.

- Why I say that this is unprovoked response, because China have every right to using her own land area as missile and firing range.  After all, Diaoyutai is suppose to be return back to China from the Article of Japanese Surrendered.   By international law, Japan is wrongfully holding these bare island and not fullfilling her WWII surrender conditions.

- Now, if these stupid Japs decided to attacking China; it will fully turn them into aggressor and recalling their bloody mayham and wanton aggression throughout Asia.

Under this condition, do you thinks Japan is going to gain much support from the rest of Asian Nations.

Should Japanese decided to attack China regardless of World opinion and the UN carter of Potsdam Protocols, do you really thinks... that Japan have the military means to attacking China directly?  The moments Japanese military attacking China, the PLA will be unleased the revenges Chinese nation being denied over Japan for the last 60 years.

Do you thinks these Japanese seeking to be leveled and terminated as a race? 

Do you know what these Japan will be like after they have attacking China proper?  I guranteed you, that Chinese revenges and response will be massive, and these Japanese will not be standing as a distinct people after this Sino-Japan War is finished.

Lucky, you are the the Japanese Prime Minister, for you surely leading the entire Japanese population into hell.
