This WSJ editorial looks beyond Speaker Nancy Pelosi's visit to Taiwan. It says for decades during which China modernized its economy with US investment and technology, Chinese policy remained peaceful reunification and no set date. The US under this agreement for peaceful reunification agreed that it would follow One China policy and not follow the earlier policy during the Cold War of close defense ties with Taiwan. Now it appears from Chinese policy under Xi Jinping that Chinese plans are for reunification of Taiwan by any means and with a date of the next decade or even in the next 18 months, says WSJ. This is a change of previous Chinese policy says WSJ and the US response should be to act with a change in its policy to provide Taiwan with the ability to defend itself during an invasion of the islands around Taiwan or other invasion.
