Facing strong opposition from Chinese government and people, the Japanese government is still obstinately sticking to a wrong course of action, and is acting arbitrarily by outrageously "buying the Diaoyu Islands." The scheming by some Japanese politicians seems to be smart but could not be further from, and these politicians are digging their own graves and will ultimately pay a heavy price.
First, Japan underestimated the Chinese people's resolution and will of defending the territory integrity of China. The time when China was poor, weak and always bullied by others has long gone.
Second, Japan is placing a heavy burden on its back. China cannot stop Japan from "playing with fire" over the Diaoyu Islands, but it has taken the moral high ground by reacting resolutely to Japan's deliberate provocation.
Third, Japan is putting its own future at risk. The Japanese economy has long been sluggish, and Japan has always hoped to hitch out of its lost two decades on China's economic bandwagon.
Fourth, Japan is losing the trust of neighboring countries and the international community. Its purchase of the Diaoyu Islands is a blatant denial of the victory of world anti-fascism war, and a serious challenge to the post-war international order. Japan's revisionist attempts are bound to make its neighboring countries and the international community more vigilant, and worsen its own diplomatic environment. It is making enemies everywhere, and will be utterly isolated and besieged on all sides once again.
Fifth, Japan wrongly believes it can do whatever it wants as long as it has U.S. backing.
All in all, the Japanese government should pull back before it is too late, implement the consensus and agreements it reached with China, and return to the negotiating table as soon as possible, otherwise it will pay an even heavier price.
