Except for the US Navy under congressionally approved treaties, must be there to defend. No matter what “China Biden” orders. Except for the Japanese Maritime self defense force which will voraciously defend Japanese territory. China must eliminate the threat from the southern Japanese territory to successfully attack Taiwan; Okinawa, Senkaku islands, etc. stand in the way. China has been interfering in Okinawa politics for decades to turn them against mainland Japan and the US. It’s been tenacious but the Okinawans still remember that the emporer sacrificed them but, ironically, the US Marines saved them (long story) Thailand, Vietnam, Philippines all have dogs in this huge fight against Chinese aggression. The only pussies in this story are Australians. They sold themselves out to the Chinese yuan.
