Today's throughline: arrangements that looked settled a few days ago are coming apart, from tariff diplomacy to alliance politics to Russia's shadow war.

Trade and alliances under strain

  • Canada and the US failed to close a deal officials called 'very close' days earlier; 50% US tariffs on C$20 billion of Canadian goods took effect Saturday, and Prime Minister Mark Carney says Ottawa will retaliate dollar-for-dollar (more).
  • The European Commission joined a growing group of countries demanding Israel scrap its E1 settlement plan, and Germany's foreign minister now says he won't rule out EU sanctions against Israel — a break from Berlin's traditional reluctance on the bloc's most consequential lever (more).

Russia's widening war

  • Ukrainian drones struck a warehouse belonging to Ozon, Russia's second-largest online retailer, in the Samara region overnight to Saturday, starting a fire and forcing roughly 500 evacuations; the same night Russian strikes on Ukraine killed at least two people (more).
  • German police are probing possible Russian links to a weapons cache found in Bavaria, one node in a week that also saw Houthi attacks on Red Sea shipping, a new Saudi maritime coalition and a Canadian debate over whether China's role in the fentanyl trade counts as hybrid warfare — researchers call this a standing doctrine, not isolated incidents (more).
