I can understand the Chinese claiming the Paracel Island group (even if Vietnam also has a legitimate claim) but the Spratly Islands? How is that Chinese territory? But don't tell the Chinese that, they want them and are probably willing to go to war over them. Will the U.S. offer any resistance? And if not there, what is going to happen to Taiwan? Given the weak response in Ukraine of Obama and Hagel, the Chinese must know that the U.S. is not going to do anything. The Chinese are ready to take on Japan north of Taiwan too.
This is very dangerous because it could quickly escalate out of control.
