 The U.S. and an array of other NATO allies will send Ukraine dozens of air defense systems in the coming months, including at least four of the powerful Patriot systems that Kyiv has been desperately seeking to help fight off Russian advances in the war. President Joe Biden made the agreement announcement at the opening of the NATO summit in Washington. The United States, Germany, the Netherlands, Romania, and Italy will provide Ukraine with the equipment for five additional strategic air defense systems.
