[4][5][6] In November 2020, he was nominated for the 2021 Nobel Peace Prize along Julio Aro, the Argentine Falklands War veteran who joined efforts with Cardozo in the DNA identification of remains in the Cemetery.

[10][3] Cardozo, a specialist in post-traumatic stress disorder (PTSD) and Spanish speaker,[11] arrived to the Falklands after the war to provide support and to check on the morale of service personnel.

[12][14] Then, Cardozo was officially charged with the task of locating and burying the remains of Argentine soldiers dispersed in the island, and the creation of a cemetery (in land donated by Brooke Hardcastle, a farmer).

[9][11][15][12][14][13] To cope with this new task, he returned to London and assembled a crew of twelve men who would assist him in the Falklands, then came back to continue with the burying.

[3] He provided Aro with a copy of his reports, indicating the location of bodies in the cemetery, which became crucial for the DNA identification of Argentine veterans remains in 2017.

[19][8][9][20][12] They also had the help of Roger Waters, who used his time in an audience with then-president Cristina Fernández de Kirchner to increase public pressure on the search.
