Roberto Eduardo Viola

His parents were Italian immigrants Angelo Viola and Rosa Maria Prevedini, both from Casatisma, a town in the Province of Pavia.

Notably, Sigaut abandoned the sliding exchange rate mechanism and devalued the peso, after boasting that "they who gamble on the dollar, will lose".

[4] The re-establishment of diplomatic ties allowed for CIA collaboration with the Argentine intelligence service in arming and training the Nicaraguan Contras against the Sandinista government.

Argentina also provided security advisors, intelligence training and some material support to forces in Guatemala, El Salvador and Honduras to suppress local rebel groups as part of a U.S.-sponsored program called Operation Charly.

Viola met with Ronald Reagan and Argentine Ambassador Jorge A. Aja Espil at the White House on March 17, 1981.
