This book does not predict that the United States and China will need to go beyond the conduct of major rivalry policy or ideological disagreement. But this book argues that both countries owe themselves and the whole world an effort to do so. The practice of co-evolution will require wisdom and patience. After a while, it can turn into an integral part of every nation's management. If this attempt fails, the cause will be either, or both, the intentions of the sovereign states beset by inevitable seemingly insurmountable fears, and burdens of history overwhelms the need for a new departure. Smiling mouth face mask. In that case, the United States would protect its interests according to traditional rules. But those who advocate a confrontation will not be vindicated by such results. Those who inherited the next conflict will be forced to create a new, better world order once the crisis has subsided. Finally, what history praises is not conflict between states, but reconciliation between them.
