Hopefully, the EU will cut Poland's funding and we'll see how the Polish government shall react ;););)
It would be fatal EU`s mistake. Similar to the decision to sanction Russia.
If come to it and if that harm Polish economy, Poland would turn to other global centers of power for new financial arrangements- China, India, Russia, Brazil,.. Then, it would just accelerate Poland`s path to Intermarium, same way as being under pressure of EU, Hungary and Serbia together entered in great projects financed by China- new fast train corridor from Budapest to Belgrade.
So no, EU would do its best to isolate Poland politically and then to initiate maiden in Poland.
