As Trump threatens Canada, where are our allies?

World leaders are gathering in Germany this weekend to discuss threats to international security, including Russia’s war on Ukraine. But for some countries — Canada included — the latest threat is coming from U.S. President Donald Trump. CBC’s defence correspondent Murray Brewster guest hosts The House to look at international crises unfolding in real time.We start with Oleksandra Matviichuk — head of the Center for Civil Liberties, which was awarded the 2022 Nobel Peace Prize — who shares her reaction to Donald Trump’s conversations with Russian President Vladimir Putin about ending the war in Ukraine.Then, as Trump continues to taunt Canada about not being a “viable” country, The House asks: where are our allies? Former NATO representatives, a former British Conservative MP and Prime Minister Justin Trudeau’s former national security advisor discuss whether Canada’s friends will stand up to the U.S. president.Plus, one man definitely knows what it's like to be under Trump’s microscope — and that’s former Illinois Republican congressman Adam Kinzinger, who voted to impeach Trump after the Jan. 6, 2021, attack on the U.S. Capitol. He joins the program to share his advice for Canada on tackling Trump.Finally, Canada’s five living former prime ministers have come together to encourage Canadians to rally behind the flag this weekend — but there was a time when the great flag debate was among the most divisive Parliament has seen. House producer Emma Godmere takes a trip back into the archives.This episode features the voices of:Oleksandra Matviichuk, head of the Centre for Civil LibertiesSveinn Helgason, former strategic communications officer at NATO HeadquartersFabrice Pothier, CEO of Rasmussen GlobalAndrew Percy, former MP and UK trade envoy to CanadaVincent Rigby, former national security and intelligence advisor to Prime Minister Justin TrudeauAdam Kinzinger, former Illinois Republican congressmanEmma Godmere, producer for CBC’s The House
