I believe there is no basis for believing that China will pose a serious threat to the U.S. any time soon. China is simply not in our league. Ours was ten times that size. In short, a Chinese threat to U.S. security interests just doesn't stand up to scrutiny. Instead of viewing China as a threat, we should seek it as an opportunity.
China is an emerging superpower.
The correct policy approach is to engage China, not isolate it. Engagement is not endorsement. It is not alliance. It is certainly not appeasement. It means actively engaging China to resolve our differences.
