I would support cooperation with Ukraine based on the exchange of technology, know-how, and practical solutions for effective collaboration.
Lovely idea, Iron; absolutely precious, quaint and magical.
Unfortunately for our delusional Polish hearts, Ukraine sh*ts on Poland rather regularly. Just recently Zelensky announced a program of joint weapons production (e.g. opening drones, missiles and air defense systems production lines in partner countries) with allies of Ukraine. Those allies are: the UK, Denmark, Norway, Germany, Canada and Lithuania. Yes, you read that right, even Lithuania gets her share.

Did you notice which country is sadly missing from this list? On the bright side, Poland is more than welcome to contribute 0.25% of our GDP to o help Ukraine increase arms production...
