Prime Minister Mark Carney of Canada landed in Japan on Friday as part of a 10-day tour that also included Australia. All three countries share at least one major concern: how to adapt now that President Trump has made it clear that they will need to look after their own security.

“First, most importantly and fundamentally, we are enhancing our security and defense cooperation,” Mr. Carney said after a brief signing ceremony.
