Yes they called Biden’s Bluff. It is a No-Win situation for Poland. If Poland flies the jets to Ukraine and any get shot down over Ukrainian territory, those were NATO jets w/Polish pilots being shot down. Article 5 NATO crap comes into play.
If Ukraine sends pilots to Poland to “pick up” the aircraft and are shot down over Ukrainian territory, NATO will be seen as “actively” providing a safe base and support for Ukrainian operations. Act of war against Russia. It would be safe to assume that those jets would leave fully fueled and armed.
If they want to send the planes so damn bad, truck them to the border and let Ukraine figure it out from there.
No Article 5 for the attacker.
