Fernández's government has complained that YPF under-invested in Argentina and has sent too much oil, and profits, abroad. Spanish Prime Minister Mariano Rajoy blasted Argentina's action, saying it lacked justification and was a 'negative decision for everyone.' Was the government justified in taking over YPF? How will the takeover affect investment in all sectors of Argentina's economy? How will the move affect Argentina's relations with other countries
