2. NATO leaders are braced for Tuesday’s summit meeting in Brussels. Above, protesters were already out on the streets there over the weekend.

European officials are anticipating more off-the-cuff remarks from President Trump, who has again been pressuring them to expand their military budgets. The NATO nations may be reluctant to push back very hard because, as one analyst points out, “They’re caught between dependency and outrage.”

After NATO, Mr. Trump will head to Britain for a few days. Protesters intend to find him wherever he goes (and aim to fly a 19-foot “Trump Baby” balloon over Parliament). Then he’ll go to Finland to meet with the Russian president, Vladimir Putin.
