Ukrainian President Volodymyr Zelensky needled the Trump administration for not agreeing to a drone-based mutual agreement months ago, now that American troops are coming under fire in the Middle East and are seeking Kyiv’s expertise.

The Ukraine-Russia war has been at the forefront of drone proliferation and modernization efforts for war fighting, which is also an area that the United States is behind on, and the Ukrainians have sought for months to exchange their newfound knowledge and technology for more advanced U.S. air defense systems that could be used to intercept more high-powered missiles that Russia also frequently deploys against them.
