prove conclusively that he was a primary cause of the end of communism. However, the major figures on all sides—not just Lech Wałęsa, the Polish Solidarity leader, but also Solidarity's arch-opponent, General Wojciech Jaruzelski; not just the former American president George Bush Senior but also the former Soviet president Mikhail Gorbachev—now agree that he was. I would argue the historical case in three steps: without the Polish Pope, no Solidarity revolution in Poland in 1980; without Solidarity, no dramatic change in Soviet policy towards eastern Europe under Gorbachev; without that change, no velvet revolutions in 1989." In December 1989, John Paul II met with the Soviet leader Mikhail Gorbachev at the Vatican and each expressed his respect and admiration for the other. Gorbachev once said: "The collapse of the Iron Curtain would have been impossible without John Paul II." On John Paul II's death, Gorbachev said: "Pope John Paul II's devotion to his followers is a remarkable example to all of us." On 4 June 2004, U.S. president George W. Bush presented the Presidential Medal of Freedom, the United States' highest civilian honour, to John Paul II during a ceremony at the Apostolic Palace. The president read the citation that accompanied the medal, which recognised "this son of Poland" whose "principled stand for peace and freedom has inspired millions and helped to topple communism and tyranny". After receiving the award, John Paul II said, "May the desire for freedom, peace, a more humane world symbolised by this medal inspire men and women of goodwill in every time and place." Communist attempt to compromise John Paul II In 1983, Poland's Communist government unsuccessfully tried to humiliate John Paul II by falsely saying he had fathered an illegitimate child. Section D of Służba Bezpieczeństwa (SB), the security service, had an action named "Triangolo" to carry out criminal operations against the Catholic Church; the operation encompassed all Polish hostile actions against the pope. Captain Grzegorz Piotrowski, one of the murderers of beatified Jerzy Popiełuszko, was the leader of section D. They drugged Irena Kinaszewska, the secretary of the Kraków-based weekly Catholic magazine Tygodnik Powszechny where Wojtyła had worked, and unsuccessfully attempted to make her admit to having had sexual relations with him. The SB then attempted to compromise Kraków priest Andrzej Bardecki, an editor of Tygodnik Powszechny and one of the closest friends of Cardinal Wojtyła before he became pope, by planting false
