Trump commits the United States to NATO's Article 5

While speaking in the White House Rose Garden on Friday, President Trump said, "I'm committing the United States to Article V, and certainly we are there to protect." While at a NATO summit last month, Trump had not explicitly voiced that commitment. According to Article 5, NATO members will come to the defense of any other country in the alliance if attacked. It was invoked for the first time after the 9/11 attacks.
