Trump makes his first trip abroad as president, traveling to Saudi Arabia, Israel, the West Bank, Italy, Vatican City, Belgium, and Italy. He attends a summit in Riyadh with leaders from more than fifty Arab- and Muslim-majority nations, where he delivers a speech calling on the Muslim world to unite against terrorism. In Brussels, Trump addresses North Atlantic Treaty Organization (NATO) heads of state and government, calling on each of them to “finally contribute their fair share” to the alliance. He does not, however, explicitly state his support for NATO’s Article 5 mutual defense clause. In Italy, Trump participates in the Group of Seven meeting, where the United States joins a joint declaration on fighting protectionism but withholds its support from one reaffirming the Paris climate accord.
