Story summary

The Australian Defence Force (ADF) is participating in war games this week in Canberra, simulating a regional conflict with China. These exercises are being run by the Washington-based Hudson Institute and involve US nuclear-powered submarines that will be based near Perth starting next year as part of the AUKUS agreement. Bryan Clark, director at the Hudson Institute, noted half the participants are from the ADF, with US and Japanese military personnel making up another quarter. The war games aim to demonstrate how these submarines would be used in a conflict scenario and underscore Australia's commitment to the AUKUS pact amid growing tensions with China.

🔮 The Democrats, Trump said, will use their newfound power “every single day for the next two years”.
🔮 And his election autopsy tried to position him as the movement’s future standard-bearer – one who would really put America first, rather than paying lip service to the idea.
🔮 Democrats could end up with as many as 56 seats in the Senate – a gain of nine – with races in Alaska and deep red Mississippi still too close to call.
🔮 And if it’s a massive win for the Democrats, it is a massive defeat for the Republicans – one which will subject Trump and his party to investigations and possibly impeachment proceedings in Congress.
🔮 The Democrats, who only needed three more seats to gain control of the House, were projected to gain upwards of 20, as Americans rebelled against an unpopular president and his war in Iran, as well as higher petrol and grocery prices caused in part by that conflict.
🔮 The temptation after a Democratic victory at today’s midterm elections – if that is indeed what transpires – will be to parse the results as Americans turning the page on Donald Trump and his Make America Great Again (MAGA) movement.
🔮 What began as a consensus that Republicans would lose their slim majority in the House of Representatives but likely retain the Senate has become a growing expectation that Democrats will win control of both chambers. However, some pollsters are nervous about the accuracy of those surveys, and reluctant to predict a “blue wave” will eventuate.
🔮 “We have a lot of great things planned for Washington – and I could get into the nation, but for that, you don’t have enough time,” he said.
🔮 Foreign Minister Penny Wong has urged the United States not to resume strikes on Iran after the midterm elections, warning it would worsen economic pressures that are driving the protests and social instability in France, Spain and elsewhere around the world.
🔮 Trump will travel to the Midwest states of Kansas and Iowa for in-person rallies on Sunday (US time), where Republicans are fighting to hold seats in the US Senate.

Narrative

But the new focus on nuclear-powered submarines, which will soon be based in Western Australia, demonstrates the AUKUS agreement progressing from theory into military practice, and underlines the seriousness with which the militaries regard a potential conflict. Clark, speaking in Washington this month, worried Australia was yet to convince the public of the utility of AUKUS and the nuclear-powered submarines it will spend tens of billions acquiring. “I feel like the ADF, the Australian government, hasn’t made the case for how they would use them and why it’s important to buy them,” Clark said.
