President Trump delivered an address in the historic Krasinski Square in Warsaw, site of the 1944 uprising against the Nazis. He talked about the spirit of the Polish people and the enduring relationship they have with the U.S. and Europe. He also addressed the “age of terrorism” that continues to threaten the peace and stability in the West and called on Russia to end its “destabilizing activities” in Ukraine. He also said he stands firmly behind the collective NATO defense principle, Article 5, but warned that “words are easy” and Europe must do more. Prior to his speech, he participated in a wreath-laying ceremony with the Polish president and was later introduced by First Lady Melania Trump.
