Scomo is dumb enough to do this, so if true he has no one else to blame.
But you look at what's happening in Australian politics in the last few days: them saying they support the One China policy, that article questioning ASPI and this investigation into Morrison say to me that Labor has judged that the China card is played out and now they are attempting a pivot. Not to become pro-China but more neutral like NZ.
Before we talk about weather or not China should respond to this possible change in tone consider how the US is feeling about this change. We got South Korea saying they don't want to join CHIP4 unless all partners say they support One China and no ban on selling chips to China and now even one of the five eyes is wavering.
