Soon, due to his cooperation and expertise, he managed to get himself appointed to carry out a similar submarine attack against a Chilean ship because tensions between Chile and Argentina were high due to the Beagle dispute. This attack was not carried out in the end because the disagreement between Chile and Argentina was finally resolved peacefully. Nicoletti was then sent to Venezuela as a spy but he was discovered and had to return to Argentina. Shortly after he settled in Miami, but when he heard of the Argentine invasion of the Falkland Islands he immediately got in touch with the Argentinian government in case his services were needed and he was instructed to return to Buenos Aires.
