Strong post Isolate, thanx for that. But Your justification is somewhat based on early 80s memorandum of Sino-US relation. There have be many changes ever since, like Trade sanction, Massive american interference in Taiwan-China issue, military co-operation to Taiwan, ongoin military deployement in Twain Straits, so on so forth. I believe there is still a buggy road for normal diplomatic relation. At present scenario US is trying possible way to bring things to normal because they know CHINA will play vital role by hosting N. Korea issue. At such a verge of wouldbe explosion at the korean penensula, US cannot play with yet another Fire. Powell statements is as comprehensive but complex as well, and he noted that as well. Yes, he said American believes in one-China but he put big "BUT" and said United States should ensure that Twain should be able to defend itself. If American ethically support one-China, why they want Taiwan to defend its sovereignty ? Why not US help China for peacefully reunification ?
