He opened the pandora box that shouldn't be opened.  Now Biden, with his neocons are thinking it is an opportunity to pressure China based on 1980s data.  

The chip fiasco with TSMC exposed the world's vulnerability and now, Taiwan needs to be protected no matter what cost.  Australia, already thinking that they need to step in based on 1980s data. They have to remember that Taiwan will never be a pawn to Western domination despite what they think.  Most Taiwanese would never want to see their cousins across the Taiwan Strait be subjected to nuclear attacks.  Taiwan just want to maintain its sovereignity which can be seen as legit ever since it transitioned from the Republic of China seeing mainland China s "rouge provinces" to an island nation wanting independence and autonomy.  That is as much as the extent it will go.  Further than that, by threatening to annihilate their cousins will have serious blowbacks that White people don't understand because they see us as inferior pawns and it is their nature.
