Actions were taken to contain the Exocet threat. A major intelligence operation was initiated to prevent the Argentine Navy from acquiring more of the weapons on the international market. The operation included British intelligence agents claiming to be arms dealers able to supply large numbers of Exocets to Argentina, who diverted Argentina from pursuing sources which could genuinely supply a few missiles. France denied deliveries of Exocet AM39s purchased by Peru to avoid the possibility of Peru giving them to Argentina because they knew that payment would be made with credit from the Central Bank of Peru. British intelligence had detected the guarantee was a deposit of two hundred million dollars from the Andean Lima Bank, an owned subsidiary of the Banco Ambrosiano.
