The Russian invasion of Ukraine began this week. Where it will end, is unclear. The world watched in horror as Russian tanks rolled across the border, bombs rained down and local civilians either hid in shelters or fled. It's an immediate crisis for Ukraine – and a longer-term test for the West. Where and how does it draw the line – to protect the rules-based global order? If Vladimir Putin succeeds in Ukraine – what's next? Prime Minister Scott Morrison is keeping his eyes on China – pressuring Beijing to condemn the Russian invasion.

Peter Dutton lobbed the first grenade – and then Scott Morrison charged in. They've both accused Labor of being China's pick – and of wanting to appease Beijing – of being soft. So extreme were some of the accusations – fellow Ministers wouldn't repeat them. Past and present national security chiefs even took the rare step of speaking out. Playing politics is unhelpful. Inventing differences – they warned - will only help China. That hasn't stopped the Prime Minister.

Recriminations continue inside the Liberal Party – over how a signature policy promised by the Prime Minister before the last election - could end in such chaos just months before the next. After a marathon all-night debate - 5 Liberals crossed the floor in the early hours of Thursday morning – exposing deep differences within the government – a divide which ultimately sank Scott Morrison's hopes of legislating a Religious Discrimination Bill in this parliamentary term. Both sides of politics want a new law to prevent discrimination against people of faith – but there are unresolved differences over how to do this while protecting gay and transgender communities. It was another hit to the Prime Minister's authority – in a week that also saw a damaging Cabinet leak – and more criticism of Scott Morrison from Brittany Higgins and Grace Tame.
