Are China and Japan going to war?

[Light House]

62. You think that the U.S, wouldn't come to the aid of Japan?

The U.S. Military and Japan's Military are intertwined and China would certainly kill American's with any strike on Japanese military units/bases.
You think President Obama would just sit by while China attacks Japan? Especially if scores of Americans were killed?

No, my friend, President Obama would order offensive military action against China's air and sea assets.

Don't forget, China's military is mainly configured for the defense of the mainland, their ability to project power beyond their borders is negligent, they have no transport capability to speak of to move troops very far and those transport aircraft they do have would be shot down PDQ by carrier aircraft.

Another thing to consider is that China knows that if they attacked Japan, they would lose their #1 market for their cheap and shoddy goods which would devastate the Chinese economy, that reason right there is why I believe that China won't attack Japan.
