From my point of view, this guy Zelensky lives in a world of his own, demands from other countries weapons, nuclear weapons, EU and NATO accession, other armaments, aircraft and artillery, but I've never read whether he pays for it.
Recently he has been calling for foreign volunteers to fight for Ukraine, you can provoke Putin so badly. Now the Ukrainian is demanding a no-fly zone, if the EU or NATO agrees, the definitive world war will start on the same day.
Until now, Putin has left his long-range bombers in the hangar, but if a European country actively enters the war against Russia, things will probably look different.
If there is a bang here, Russia will be the first to flatten every US base in Germany, and by that I mean really flat, it will then get burning hot very quickly.
