There is no question that China and Iran are developing a close relationship that is detrimental to Israel. They are developing a nuclear bomb. As a result China is now rich enough to short-cut its rise as a superpower by buying Russia hardware and technical assistance. Russia needs the money and China can pay. Historically China's enemy, India is emerging as a colossus that rivals China in population but not military prowess.
Asian conflict seems inevitable.
In short, the emergence of China as a superpower is a fact. Its implications for the world remain somewhat ominous. It is not a safer world.
