Or better yet, instead of abandoning our military gear in Afghanistan, we should have filled up C-17's and delivered it to Ukraine and maybe South Korea and Taiwan, as well. Plenty of good stuff now in enemy hands thanks to the way the withdrawal was run by the Biden administration.
As for the Polish jets:
Biden 'personally killed Polish jet deal' despite Republican AND Democrats ramping up calls to give Ukraine combat planes to make Putin 'fearful of what WE might do'

Despite desperate please from Ukrainian President Volodymyr Zelensky and pressure from lawmakers at home, President Biden killed the Polish plan to transfer MiG-29 jets to Ukraine, fearing the deal might be viewed as an escalation of tensions by Vladimir Putin.
The diplomatic blunder that began with a top European Union diplomat promising the jets to Ukraine ended when Poland suggested it would give the jets to the U.S. to deliver to Ukraine, and the U.S. said that was Poland's responsibility.
Then, U.S. defense officials killed the project entirely, saying they would not support either transferring the jets themselves or backing up Poland in doing so.
