It is about the author's greatest worry: The US being surpassed by China in military strength: Obama's outdated losing strategy of Air-Sea Battle to China's space era strategy of integrated space and air capabilities: Obama's losing diplomacy that has given rise to Russian-Chinese alliance Detailed Description of China quickly catching up and surpassing the US in weapon development. It's high time for the US to adjust its strategy, diplomacy and weapon development to maintain its world leadership. Without democracy, China cannot prevent the emergence of a tyrant like Mao Zedong when it has surpassed the US. Like Mao, the tyrant may bring disasters to world people. Only a United States as strong as or stronger than China can stop the tyrant. Is the author meddling? He is a Chinese, but since the US is world leader, it belongs to world people including the author. The author certainly has the right to request improvement in the leadership.
