Nuno Rogeiro was an international relations teacher at the Lusíada University in Lisbon. He worked in multiple positions for several Portuguese newspapers like O Dia, A Rua, O Século, and O Diabo. In addition, he wrote for O Independente newspaper and K magazine during the 1990s, and worked for TSF and Rádio Comercial radios. However, it was in television that Nuno Rogeiro reached notability as a geopolitics expert and a commentator in international political and military issues. Nuno Rogeiro started his career on the television, working for Radiotelevisão Portuguesa (RTP) in 1989. During the 1991 Gulf War, Rogeiro appeared on a daily basis to comment the conflict. In 1992, he wrote Política for the collection O que é, published by Quimera. In 2003, with the eruption of the 2003 Iraq War, Nuno Rogeiro was invited by SIC TV channel, a surprise since he had always worked with RTP before then. After the 9/11 attacks in the United States, Nuno Rogeiro wrote O Inimigo Público - Carl Schmitt, Bin Laden e o Terrorismo Pós-Moderno, which was published in 2003. Along with Martim Cabral, Nuno Rogeiro presented the television programme Sociedade das Nações in SIC Notícias.[1] He has been invited for conferences on international affairs worldwide. Rogeiro co-founded the magazine Futuro Presente with Jaime Nogueira Pinto.
