Trump Questions US Commitment to Defend Allies Before NATO Meets

President Donald Trump cast doubt on exactly how far the US is prepared to go to defend its NATO allies as he headed to a crucial summit with leaders of the military alliance.

Trump said it “depends on your definition” when he was asked if he would commit to NATO’s Article 5, which requires members to defend each other from attack, while traveling aboard Air Force One on Tuesday to the summit in The Hague.
