 In 2009, after publication of another biography connecting him with the secret police (Lech Walesa: Idea and History by Pawel Zyzak), Wałęsa threatened to leave Poland if historians continue to question his past. He said that before revealing such information "a historian must decide whether this serves Poland". After the accusations against him resurfaced with the discovery of the Kiszczak dossier on 16 February 2016, Wałęsa called the files "lies, slander and forgeries", and said he "never took money and never made any spoken or written report on anyone". He said of the Polish public, which was about to believe in the allegations, "you have betrayed me, not me you" and "it was I who safely led Poland to a complete victory over communism". On his blog on 20 February 2016 Wałęsa said in the 1970s a secret police officer begged him to sign the financial documents because this officer lost money handed to him to purchase a vehicle. Wałęsa appealed to this officer to step forward now and clear him of the accusations.
