Wall Street Journal opinion piece by Michael Ledeen --
The Reagan administration—driven by a desire to gain the release of the American hostages—famously sought a modus vivendi with Iran in the midst of the Iran-Iraq War during the mid-1980s. To that end, the U.S. sold weapons to Iran and provided military intelligence about Iraqi forces. High-level American officials such as Robert McFarlane met secretly with Iranian government representatives to discuss the future of the relationship. This effort ended when the Iran-Contra scandal erupted in late 1986.
Question: Who was the crucial intermediary between the US, the Iranians, and the Israelis (who actually supplied the weapons to Iran)?
Answer: Michael Ledeen!
