two months by Resolution 1439, ended on 19 December. In August 2002, UNITA declared itself a political party and officially demobilised its armed forces. That same month, the United Nations Security Council replaced the United Nations Office in Angola with the United Nations Mission in Angola, a larger, non-military, political presence. The civil war produced four million internally displaced persons (IDPs), one third of Angola's population. The government spent $187 million settling IDPs between 4 April 2002 and 2004, after which the World Bank gave $33 million to continue the settling process. Militant forces laid approximately 15 million landmines by 2002. The HALO Trust charity began demining in 1994, destroying 30,000 by July 2007. There are 1,100 Angolans and seven foreign workers who are working for HALO Trust in Angola, with operations expected to finish sometime between 2011 and 2014. Human Rights Watch estimates UNITA and the government employed more than 86,000 and 3,000 child soldiers respectively, some forcibly impressed, during the war. Human rights analysts found 5,000 to 8,000 underage girls married to UNITA militants. Some girls were ordered to go and forage for food to provide for the troops. If the girls did not bring back enough food as judged by their commander, then the girls would not eat. After victories, UNITA commanders would be rewarded with women who were often then sexually abused. The government and UN agencies identified 190 child soldiers in the Angolan army and relocated seventy of them by November 2002, but the government continued to knowingly employ other underage soldiers. Fernando Vendrell produced and Zézé Gamboa directed The Hero, a film about the life of average Angolans after the civil war, in 2004. The film follows the lives of three individuals; Vitório, a war veteran crippled by a landmine who returns to Luanda, Manu, a young boy searching for his soldier father, and Joana, a teacher who mentors the boy and begins a love affair with Vitório. The Hero won the 2005 Sundance World Dramatic Cinema Jury Grand Prize. A joint Angolan, Portuguese, and French production, Gamboa filmed The Hero entirely in Angola. José Eduardo dos Santos stepped down as President of Angola after 38 years in 2017, being peacefully succeeded by João Lourenço, Santos' chosen successor. However, President João Lourenço started a campaign against corruption of the dos Santos era. In November 2017, Isabel dos Santos, the billionaire daughter of former President
