Explanation:

The Iran-Contra scandal, also known as Irangate, was a political event that took place in 1985 and 1986, in which senior officials of the United States government, under the administration of President Ronald Reagan, facilitated the sale of arms to Iran, a country against which an arms embargo weighed. Both operations, the sale of arms and the financing of the Contra, were prohibited by the US Senate.

The operation to sell arms to Iran produced more than 47 million dollars, money that was managed by Oliver North through a network of bank accounts in Switzerland and was used, mainly, to finance the aggression against the government of Nicaragua and support to the Contra.
