World Jewish Congress President Ronald S Lauder
"During his term in office, President Kirchner brought Argentina back on track - not just economically, but also morally, with respect to the human rights violations of the past, especially under the military dictatorship in the 1970s. Both the late President Kirchner and his wife, current President Cristina Fernandez, have played a tremendous role in ensuring that Argentina today is one of the world's foremost democracies, where the civil rights of all religious and ethnic minorities are respected."
