With Obama in charge—he hasn’t the will to fight. Japan would be on her own (maybe Vietnam could help) I don’t see USA moving because of all the debt we owe China. The worst think that would happen is US People boycotting Wal Mart. That being said—Japan has a long tradition of Naval warfare—China doen’t. Even without US help—Japan might defeat China at sea—but would China go Nuclear? Would Japan counter in some way? How long would it take Japan to build and deploy an A-Bomb? A week or two? EMP attacks and Cyber Attacks would be used in this new form of war. In this Japan has the edge. If Japan had India on her side (or Russia?) the war would be won without Obama’s Chicken do do America.
“How long would it take Japan to build and deploy an A-Bomb? A week or two?”
To build one? About 30 minutes. Deploy one? Depends on the platform.
“I don’t see USA moving because of all the debt we owe China.”

Not that Barack Hussein Obama would do it (p#ss be upon him), but repudiation of debt would be a reason for the U.S. to escalate.
