Over three consecutive days this month, Romanian F-16s shot down three drones that had entered the country’s airspace — the first such engagements over Romanian territory. One appears to have been an Iranian-designed Shahed of the kind Russia uses against Ukraine. Romania did, using Romanian pilots and aircraft, without requiring a new American deployment. In May, a Romanian F-16 flying NATO’s Baltic Air Policing mission had already destroyed a stray drone over Estonia. A withdrawal that weakens American access would create openings Russia could test, and China could exploit.
