President Trump escalated his feud with German Chancellor Angela Merkel on Tuesday, taking to Twitter to threaten Germany over trade and NATO. Trump tweeted, “We have a MASSIVE trade deficit with Germany, plus they pay FAR LESS than they should on NATO & military. Very bad for U.S. This will change.” Trump’s complaints come after Chancellor Merkel called her meetings with Trump at the G7 summit over the weekend disappointing and said Europe had to take its fate in its own hands. European allies have expressed particular frustration over Trump’s refusal to commit the United States to fulfilling its pledges to the landmark 2015 Paris climate accord. The New York Times reports Trump’s inner circle is fiercely divided on the Paris climate accord, with chief strategist Steve Bannon and EPA administrator Scott Pruitt demanding Trump withdraw from the landmark accord, while Secretary of State Rex Tillerson and Trump’s daughter and adviser Ivanka Trump are advocating for the agreement. On Tuesday, United Nations Secretary-General António Guterres called on the U.S. to remain a party to the landmark agreement.

Secretary-General António Guterres: “The effects of climate change are already being felt around the world, and they are dangerous, and they are accelerating. And so my argument today is that it is absolutely essential that the world implements the Paris Agreement and that we fulfill that duty with increased ambition. And the reason is threefold. Climate change is undeniable. Climate action is unstoppable. And climate solutions provide opportunities that are unmatchable.”
