It’s their deep state. Thank you Mr. Trump.
The newest government of Poland has been trying to do housecleaning since they won in a landslide a few years back.
That housecleaning has included changes to the judiciary saddled with judges who were persons who, following the fall of the communist government, merely took off their communist coat and put on “democratic” ones. They were allowed to do that due to a bargain with the devil Polands new democratic parties made with the old Polish communist apparatchiks, to avoid a violent upheaval and smooth the transition to elections. That judiciary was tainted by the communist past of many of its memebers and many such members were preventing true democratic reforms in Poland.
Eseentially the “socialist” and their old friends from the communist government were working together to keep Conservatives down, out of power and unable to reform things.
By the EU, the EU has complained about the judicial reforms - because it was their Leff of center friends in Poland who had been protected by the old status quo.
Now the government of Poland is going after the nests of treasonous forces in the state diplomatic corps. That is long overdue as well.
