The island chain strategy was originally created by john foster dollas. The idea is, if you want to bottle up and contain china, you do it by controlling these island chains. And tian is really the central one. It sort of divides this east china sea where you've got south cree and japan,. Where you've got vianam and malasia, distant between via nam and japan. But if you really wo in this way, as does sax ougre, china has flip flopped on this. Only the last hundred years that they've really considered tiwan strategic. They didn't care about it two or 300 years ago. Yidon
