In last April Hodges claimed Crimea is going to get back under Ukraine by November.
As a side note, what happened to hundreds of Ukrainian jets they had prior?
Corruption - lots of aircraft unserviceable before the war for no good reason.
Destroyed on the ground at their airfields.
Brought down by Russian AA.
Lack of parts - Ukrainian jets were mostly made in other parts of the former USSR that are now Russia or interdicted by Russia, so they can’t get wear parts. Or munitions.
