Of course, Polonius conveniently forgets to mention that Jarosław was also heavily involved.
Jaroslaw Kaczynski is presented today as an ardent supporter of the government of Jan Olszewski
It was the direct opposite. Olszewski was the Prime Minister on behalf of the Center Agreement, he was their candidate from Warsaw that took second place (first place was Kaczynski, and the third Glapiński). When Olszewski became Prime Minister, he began to build their camp at the expense of Kaczynski and his colleagues from the Center Agreement. He fought for the leadership of the party. Olszewski has not been able to build his government , because Kaczynski continually tried to take the initiative and build a majority.
As always with PiS, they have a strong habit of distorting the truth. As above...
(Those who love watching the lies of PiS might wish to note that Kurski is now boss of TVP)
One explanation - why PiS tries to trash Lech Wałęsa and others - is that PiS is trying to write its founding myth.
I think so too. They are a party built on hate, and that hatred comes out towards anyone that opposes them. I'm almost certain that if it was revealed that JPII said that Kaczyński was a poisonous individual, they would build some cult against him too.
