On foreign policy, a confident Trump removes his training wheels

In the days preceding last July’s NATO summit in Brussels that President Trump was set to attend, administration officials including Defense Secretary James Mattis worked around the clock with European allies to seal a summit declaration before the alliance leaders’ meeting even began. The rush by Mr. Mattis and others to complete a deal they knew might not sit well with their boss – who had consistently aired his doubts about the benefits of international defense alliances like NATO and his disdain for what he considered to be freeloading allies – was striking. What it displayed was one more example of Mr. Trump’s top national security advisers working around the president’s skepticism and unpredictability toward traditional allies to confirm America’s unaltered global leadership role.
