Never giving up their pressure on the regime, after the military gave up its authority to a civilian government in 1983, the Mothers of Plaza de Mayo rekindled hopes that they might learn the fates of their children, and pushed again for the information. Beginning in 1984, teams assisted by the American geneticist
Mary-Claire King began to use
DNA testing to identify remains, when bodies of the "disappeared" were found. The government conducted a national commission to collect testimony about the "disappeared", during which they heard from hundreds of witnesses. In 1985, it began the prosecution of men indicted for crimes, beginning with the
Trial of the Juntas. Several high-ranking military officers were convicted and sentenced as a result. The military threatened a coup to prevent a widening of prosecutions. In 1986, Congress passed
Ley de Punto Final, which stopped the prosecutions for some years. But in 2003, Congress repealed the Pardon Laws, and in 2005 the Argentine Supreme Court ruled them unconstitutional. During the Kirchner administration, the prosecution of war crimes was re-opened. Former high-ranking military and security officers have been convicted and sentenced in new cases. Among the charges is the stealing of babies of the disappeared. The first major figure,
Miguel Etchecolatz, was convicted and sentenced in 2006. Most of the members of the Junta were imprisoned for
crimes against humanity. With the
Grandmothers of Plaza de Mayo, a group set up in 1977, the Mothers have identified 256 missing children who were adopted soon after being born to mothers in prison or camps who later "disappeared". Seven of the identified children have died. At the beginning of 2018, 137 of those children, now grown adults, were found and were offered the chance to meet their biological families. Some Mothers and Grandmothers suffered disappointments when the grandchildren, now adults, did not want to know their hidden history, or refused to have their DNA tested. Parents who were judged in court to be guilty of adopting – or "appropriating" – the children of the disappeared, while knowing the truth about their origins, were susceptible to imprisonment. In 1986, the Mothers split into two factions. One group, called the , focused on
legislation, the recovery of the remains of their children, and bringing ex-officials to justice.
Hebe de Bonafini continued to lead a more radical faction under the name Mothers of Plaza de Mayo Association. These mothers felt responsible for carrying on their children's political work and assumed the agenda that originally led to the disappearance of the dissidents. Unlike the Founding Line, the association refused government help or compensation. They pledged not to recognize the deaths of their children until the government would admit its fault. A scholar of the movement,
Marguerite Guzman Bouvard, wrote that the association faction wanted "a complete transformation of Argentine political culture" and "envisions a socialist system free of the domination of special interests". The Mothers Association is now backed by younger militants who support socialism. In the wake of the attacks on United States on
11 September 2001, Bonafini said "I was happy when I first heard the news, that for once they were the ones attacked, I'm not going to lie." She said that "the U.S.A [was] the most terrorist of all countries, throwing bombs everywhere around the world" but "felt bad for the innocent workers dead (because of the terrorist attack)." Her remarks were criticised in mainstream media. Speaking for the Mothers, Bonafini rejected the government's investigations of alleged
Iranian involvement in the 1994
AMIA Bombing (the terrorist attack on the AMIA
Jewish community center), saying the
CIA and
Mossad were misleading the investigation. She said that they repudiate "the tragic attack, but respect for the victims and their families requires to investigate and do justice," without being "politically manipulated in the service of US interests." =='Final' March of Resistance==
