[3] In the position of Counter-terrorism Advisor Nir played a key role in the Israeli response to the 1985 Achille Lauro hijacking.
[3] He resigned from the Israeli government in March 1987,[3] after public criticism of his role in the affair (and with his US contact Oliver North attempting to pin the blame on Nir) made him feel "neutralized of his authority".
[9] His body was also identified in the crash wreckage by Pedro Curchet, an Argentinian associate of Nir who worked for the avocado-exporting venture, Eupasa.
[12] Given his connections to the Iran–Contra scandal, Nir's death sparked conspiracy theories that he was murdered to prevent him from revealing embarrassing details about then-President-elect of the United States George H. W.
[12] On a different Israeli television program in 2014, Nir's son Nimrod stated that after years of investigating his father's death, he believed it was an assassination and suggested Bush was responsible.
