The range of support for the Solidarity was unique: no other movement in the world was supported by Ronald Reagan, Santiago Carrillo, Enrico Berlinguer, Pope John Paul II, Margaret Thatcher, Tony Benn, peace campaigners, NATO Spokesman, Christians, Western Communists, Conservatives, Liberals, Socialists. The international community outside the Iron Curtain condemned Jaruzelski's actions and declared support for Solidarity; dedicated organizations were formed for that purpose (like Polish Solidarity Campaign in Great Britain). US President Ronald Reagan imposed economic sanctions on Poland, which eventually would force the Polish government into liberalizing its policies. Meanwhile, the CIA together with the Catholic Church and various Western trade unions such as the AFL-CIO provided funds, equipment and advice to the Solidarity underground. The political alliance of Reagan and the Pope would prove important to the future of Solidarity. The Polish public also supported what was left of Solidarity; a major medium for demonstrating support of Solidarity became masses held by priests such as Jerzy Popiełuszko.
