Why aren't those Polish MIGS being delivered to Ukraine "yet"?

Maybe later? Why aren't those Polish MIGS being delivered to Ukraine "yet"?

Reading between the lines and some speculation.  Listen carefully what is coming out of the Pentagon this past week..

 Russia is under scrutiny for war crimes in targeting civilians..and their generals are liable. (per the Hague war times trials in the Bosnian war)Corridors are being announced to give civilians a chance to evacuate. Russia is threatening to use air attacks on EU and US supply lines to resistance fighters.. Yet...listen to what is being said: by the Pentagon " now is not the time, maybe later, via the migs." So far neither the resistance nor the Russians have made full use of their air capabilities.  So what are they waiting for? I wonder if the air war is in a pause to give resupply and evacuations a chance...and then the migs will deployed. It is not supplying the migs that risks direct confrontation with Russia and WWIII. It is who is flying them and pulling the triggers. Also within Russian boundaries, their anti aircraft missiles have a 200 mile range. Just my surmise. Let's see if this plays out. Once we get the civilians out...then the migs will be delivered to the resistance. The original estimate of refugees was 6 million and half of those are still internally displaced.
