The recent launch of Russian drones into Polish airspace generated global headlines, but the incident was far from unprecedented. If Russian drones can cross into Poland unchecked, the next stage may be for missiles to begin “accidentally” striking NATO territory. The appearance of Russian drones in the skies above Poland set off alarm bells in a number of European capitals. Following the recent Russian incursion into Polish airspace, European countries now recognize that they need to urgently study Ukraine’s unrivaled experience of defending against Russian missiles and drones. Other countries will no doubt soon be joining the Poles in seeking the advice of Ukrainian air defense crews.
