What did the Trump-Putin summit achieve — and what comes next for Ukraine? CBC senior defence reporter Murray Brewster helms this security-focused episode of The House, featuring a debrief with former U.S. diplomat Michael Carpenter on what came out of the sit-down between the U.S. and Russian presidents late Friday in Alaska.

Then, two Canadian experts — a former NATO assistant secretary general and a former naval commander — dive deep into whether Canada can realistically reduce its dependence on U.S. military equipment and support.

Also: as global leaders watch closely for what could happen next in Ukraine, Chief of the Defence Staff General Jennie Carignan discusses what possible role Canada could have in any ceasefire — and whether armed forces have the bench strength for a prolonged engagement.

Finally, Canadian researcher and author Alicia Wanless joins The House to explain why she believes the world’s democracies should look to the past — the far past — as governments continue to fight against disinformation.

• Michael Carpenter, former U.S. ambassador and permanent representative to the Organization for Security and Cooperation in Europe, now senior fellow for transatlantic affairs at the International Institute for Strategic Studies
• Wendy Gilmour, former NATO assistant secretary general for defence investment

A new nuclear reactor. A natural gas pipeline extension. Thousands of offshore wind turbines.

And how realistic – and expensive – are these plans?
