US Ambassador to NATO Matthew Whitaker: "President Trump, while he is patient, and he is a dealmaker and he wants peace - at the same time, he knows that Iran cannot have a nuclear weapon. That is the starting point, that is the red line, and unlike other presidents, President Trump, when he draws a red line, he enforces it."
The U.S. stands with Romania after a "reckless incursion" into its territory. NATO will defend "every inch" of allied land. Support expressed for those injured in Galați.
Under President Trump, our mission in Brussels has been clear: transitioning the conventional defense of Europe to our Allies. The U.S. remains a committed partner, but Allies must step up and take over.
U.S to NATO Ambassador Matthew Whitaker: “President Trump is evaluating and reevaluating everything. Whether that is our involvement at NATO… whether that is our support to the European efforts in Ukraine… or anything else the United States is doing. Everything is on the table.”
Whitaker on NATO: “It’s got to be a two-way street. There needs to be some benefit for the United States, otherwise we’re just guaranteeing Europe’s security without reciprocity.”
