You missed the:

and the few that are, aren't allied enough with the u.s. to plan there defense around u.s. support

None of those besides taiwan, japan and maybe Philippines are or should be planning there defense around u.s. support. The u.s. has no policy or interest in supporting a war over the south China sea.

Also Myanmar is more focused on there own civil war then any threats from China or the message this interview gave. If they were so threatened, they wouldn't have allowed China to be a mediator to end the conflict.
