After the October 23, 1983 bombing of American and French barracks in Beirut by the Shia group the Islamic Jihad Organization that killed 241 American and 58 French personnel, parts of the American and French governments (particularly secretary of state George P. Schultz) wanted to launch retaliatory attacks against Iranian and Iranian-aligned Shia positions in Lebanon. However, secretary of defense Caspar Weinberger was against retaliation because it wasn't certain that the Iranians and/or Hezbollah were behind the attack, so there was no major retaliation, and the Multinational Force withdrew from Lebanon in February 1984. What if Weinberger had been overruled and retaliation was ordered? Could the US and/or France have been drawn into a Vietnam-like quagmire in Lebanon? Or a war with Iran? What would be the impact on the course of the Lebanese Civil War? On the politics of the US, France, Lebanon, Iran, Syria, Israel, the PLO...?
