You are right about Kissinger (and Nixon) being the fathers of this policy, but the above does not reflect it.
This is a major problem. Over the decades most people have come to think something along the lines of your description is the policy. And the policy is morphing in to it.
But Kissinger's policy was much more subtle and clever -- maybe too much so.
The one China policy is simply that we acknowledge the Chinese position that there is one China.
Can you document that?
