Boosting the neo-Keynesian economic policies laid by Duhalde, Kirchner ended the economic crisis attaining significant fiscal and trade surpluses, and rapid GDP growth. Under his administration, Argentina restructured its defaulted debt with an unprecedented discount of about 70% on most bonds, paid off debts with the International Monetary Fund, purged the military of officers with dubious human rights records, nullified and voided the Full Stop and Due Obedience laws, ruled them as unconstitutional, and resumed legal prosecution of the Junta's crimes. He did not run for reelection, promoting instead the candidacy of his wife, senator Cristina Fernández de Kirchner, who was elected in 2007 and subsequently reelected in 2011. Fernández de Kirchner's administration established positive foreign relations with countries with questionable human rights records, including Venezuela, Iran, and Cuba, while at the same time relations with the United States and United Kingdom became increasingly strained. By 2015, the Argentine GDP grew by 2.7% and real incomes had risen over 50% since the post-Menem era. Despite these economic gains and increased renewable energy production and subsidies, the overall economy had been sluggish since 2011.
