Poor communication on the US side wouldn’t explain Poland’s “we are sending expensive war materiel via this specific location (Rus pls don’t intercept lol XD)” announcement.
Russians would know very well that MiGs are flying from Poland no matter whether they would go trough Germany or not.
And they would have to track them precisely in order to attack in both cases as well.
The stupid part was going with the MiGs transfer public in the first place back at the beginning of the war.
But I recall it came from EU official and Ukrainians, not from Polish government directly.
