Air to air missiles, missile radar alert systems, fuel tanks for fighter bombers and gas masks were dispatched from Israel apparently destined for Peru but were then transported on to Argentina, it claims.
As the British Task Force sent to reclaim the islands after the 1982 Argentine invasion of the Falklands began to get the upper hand, Argentina's ruling military junta was left with few choices from which to source replacements for equipment lost in war.
But according to 'Operation Israel: the rearming of Argentina during the dictatorship (1976/1983)' the junta found that Begin was willing to strike an agreement.
Interviews conducted by the author of the book, the Argentine journalist Hernan Dobry, reveal that Begin saw the deals as a form of revenge for the hanging of a personal friend, Dov Gruner, by the British Mandatory Authorities in Palestine in 1947.
After the Argentine Air Force contacted Isrex, the Israeli defence company, a meeting was arranged between representatives of the company and Begin.
