Although there is a perception in the public memory that the cold war outsourced fighting to what we now call the global south, with the two superpowers avoiding direct military clashes, this is in fact not the case. There were several incidents in the early 1950s that involved US aircraft being attacked by Soviet interceptors. Two of these incidents in April 1950 and in June 1952 occurred over the Baltic Sea.
Alleged Russian violations of Estonian and German airspace after its drone incursion in Poland have put NATO on edge. In the past week, Russia has ramped up a diplomacy of intimidation in the Baltic Sea using planes, drones and words aimed at Ukraine's European allies. After threats towards Finland earlier in September, Russia violated Estonian airspace on Friday and German airspace on Sunday, days after it had flown two dozen drones into Poland.
Please note that due to the threat of unmanned aerial vehicle (UAV) strikes in regions of Ukraine bordering Poland, military aircraft have begun operating in our airspace.
(We are) drawing the world's attention to this unprecedented Russian drone attack on a member of the UN, EU, and Nato, deputy prime minister and foreign minister Radosaw Sikorski told RMF FM radio. I have spoken before the UN security council in the past, and it seemed to me that our arguments resonated, that they broke through. We have not yet decided who will speak on behalf of Poland, he said.
