2017 NATO Summit: Trump Omits Article 5 Endorsement

At the opening of NATO's new Brussels headquarters, Trump delivers a speech focused on burden-sharing and terrorism but conspicuously omits any mention of Article 5 collective defense — the first sitting US president to do so at a NATO summit. National Security Advisor McMaster, SecDef Mattis, and Secretary Tillerson had all unsuccessfully tried to insert Article 5 language into the speech.
