In 1982, Pope John Paul II privately issues a letter to the communist Polish government, stating that he will resign from the papacy and return to his hometown unless they cease their repression of counterrevolutionary movements in Poland, particularly the Solidarity trade union. Called the Warsaw Letter, it was later forwarded to Moscow, enraging Committee for State Security (KGB) director Yuri Andropov. He decides to plan for the pope’s assassination, which he believes would reinvigorate Communism in Eastern Europe, perceived by many to be in a state of decline. Known only by its designated number 15-8-82-666 for security reasons, the assassin is then selected as a Turk Muslim (understood to be Mehmet Ali Ağca), who would then be eliminated by Bulgarian KDS officer Boris Strokov afterwards for deniability. The operation was later unanimously approved by the Politburo.
