What we’re watching: The subnational US-Canada relationship, Golden Dome’s leaden weight, MAGA Iran crackup

Premiers meet with governors to shape US-Canada relations

While the national level drama played out between Donald Trump and Mark Carney at the G7 in Kananaskis, a lot of important US-Canada work was going on with far less fanfare in Boston, where five Canadian premiers met with governors and delegations from seven US states. The groups talked trade and tariffs, reflecting a Canadian strategy of working through deep state-level relationships to help manage the broader tensions with Trump and his policies.

The double-price Carney would pay for the Golden Dome

As he left the G7 meeting in Alberta, Donald Trump said the price tag for Canada’s participation in the US Golden Dome missile defense project would come in at a hefty US$71 billion. Trump expects Canada to join.“They want to be a part of it,” he said. But Canadians themselves aren’t so keen. A recent poll found that 63% of respondents do not want Canada to join the shield, meaning Prime Minister Mark Carney, who has expressed openness to the idea, is caught between placating Trump or siding with the skeptical majority of his constituents.

MAGA-splits over US intervention in Iran

As the world waits to see if the US will join Israel in attacking Iran – and potentially pressing for regime change – the MAGA-Republican coalition is divided. Hardcore America First voices like Marjorie Taylor Greene, Steve Bannon, and Tucker Carlson say no way, while most establishment Republicans and Democrats are still in favor. A new poll finds that while nearly two-thirds of Americans would view a nuclear-armed Iran as a threat to the US, a slim majority of Republicans want nothing to do with Israel’s current efforts to destroy Iran’s nuclear program militarily. Overall, 56% of those polled said they favor negotiations to rid Iran of nuclear weapons.
