Nikki Haley declared on Tuesday that the U.S. will not compromise on its support for the European Union and NATO in its quest to improve relations with Russia. “The United States thinks it’s possible to have a better relationship with Russia—after all, we confront many of the same threats,” the U.S. Ambassador to the United Nations, said at a meeting of the Security Council. She singled out Russia over its attempts to “destabilize” Ukraine, adding: “Greater cooperation with Russia cannot come at the expense of the security of our European friends and allies.” U.S. President Donald Trump has cheered efforts to break up the European Union, most notably the U.K.’s vote to leave the bloc. Additionally, White House Chief Strategist Stephen K. Bannon is an ardent supporter of nationalist movements throughout the continent which promote a breakdown of the EU. Over the weekend in Brussels, Vice President Mike Pence said the U.S. is completely committed to both the EU and NATO.
