On the day of McFarlane's resignation, Oliver North, a military aide to the United States National Security Council (NSC), proposed a new plan for selling arms to Iran, which included two major adjustments: instead of selling arms through Israel, the sale was to be direct at a markup; and a portion of the proceeds would go to Contras, or Nicaraguan paramilitary fighters waging guerrilla warfare against the Sandinista National Liberation Front#1984 election Sandinista government, claiming power after an election full of irregularities.Washington Post at the time. The dealings with the Iranians were conducted via the NSC with Admiral Poindexter and his deputy Colonel North, with the American historians Malcolm Byrne and Peter Kornbluh writing that Poindexter granted much power to North "...who made the most of the situation, often deciding important matters on his own, striking outlandish deals with the Iranians, and acting in the name of the president on issues that were far beyond his competence. All of these activities continued to take place within the framework of the president's broad authorization. Until the press reported on the existence of the operation, nobody in the administration questioned the authority of Poindexter's and North's team to implement the president's decisions". North proposed a $15 million markup, while contracted arms broker Ghorbanifar added a 41% markup of his own. Other members of the NSC were in favor of North's plan; with large support, Poindexter authorized it without notifying President Reagan, and it went into effect. At first, the Iranians refused to buy the arms at the inflated price because of the excessive markup imposed by North and Ghorbanifar. They eventually relented, and in February 1986, 1,000 TOW missiles were shipped to the country. From May to November 1986, there were additional shipments of miscellaneous weapons and parts.
