1. President Trump has delivered a blunt message to NATO allies: Spend more, or else.

We gathered details of Mr. Trump’s letters to the leaders of countries including Germany, Canada, Norway and Belgium, chastising them for not increasing defense financing.

It was the latest sign of acrimony between the U.S. and its traditional allies ahead of a NATO summit meeting next week. That meeting may well be overshadowed by another immediately following: Mr. Trump’s formal solo with Vladimir Putin, the Russian president.

We also have details of Mr. Trump’s phone call with the Mexican president-elect, Andrés Manuel López Obrador. The conversation, about immigration and trade, seems to have gone well.
