In 1982, at the height of the Siege of Beirut, Mother Teresa rescued 37 children trapped in a front line hospital by brokering a temporary cease-fire between the Israeli army and Palestinian guerrillas. Accompanied by Red Cross workers, she traveled through the war zone to the devastated hospital to evacuate the young patients.
When Eastern Europe experienced increased openness in the late 1980s, she expanded her efforts to Communist countries that had previously rejected the Missionaries of Charity, embarking on dozens of projects. She was undeterred by criticism about her firm stand against abortion and divorce stating, "No matter who says what, you should accept it with a smile and do your own work." She visited the Soviet republic of Armenia following the 1988 Spitak earthquake, and met with Nikolai Ryzhkov, the Chairman of the Council of Ministers.
Mother Teresa traveled to assist and minister to the hungry in Ethiopia, radiation victims at Chernobyl, and earthquake victims in Armenia. In 1991, Mother Teresa returned for the first time to her homeland and opened a Missionaries of Charity Brothers home in Tirana, Albania.
By 1996, she was operating 517 missions in more than 100 countries. Over the years, Mother Teresa's Missionaries of Charity grew from twelve to thousands serving the "poorest of the poor" in 450 centers around the world. The first Missionaries of Charity home in the United States was established in the South Bronx, New York; by 1984 the order operated 19 establishments throughout the country.
The spending of the charity money received has been criticized by some. Christopher Hitchens and the German magazine Stern have said Mother Teresa did not focus donated money on alleviating poverty or improving the conditions of her hospices, but on opening new convents and increasing missionary work.
Additionally, the sources of some donations accepted have been criticized. Mother Teresa accepted donations from the autocratic and corrupt Duvalier family in Haiti and openly praised them. She also accepted 1.4 million dollars from Charles Keating, involved in the fraud and corruption scheme known as the Keating Five scandal and supported him before and after his arrest. The Deputy District Attorney for Los Angeles, Paul Turley, wrote to Mother Teresa asking her to return the donated money to the people Keating had stolen from, one of whom was "a poor carpenter". The donated money was not accounted for, and Turley did not receive a reply.
