Many will recall with pain what we went through in the Reagan administration in 1983, when the Marine barracks were bombed in Beirut-241 Marines and Navy corpsmen were killed. We immediately got an intercept from NSA [National Security Agency], a total smoking gun from the foreign ministry of Iran, ordering the murder of our Marines. Nothing was done to retaliate. Instead, we did exactly what the terrorists wanted us to do, which was to withdraw. Osama bin Laden has cited this as one of his dawning moments.
