The 1983 report of the U.S. Department of Defense Commission's on the attack recommended that the National Security Council investigate and consider alternative ways to reach "American objectives in Lebanon" because, "as progress to diplomatic solutions slows," the security of the USMNF base continues to "deteriorate." The commission also recommended a review for the development of a broader range of "appropriate military, political, and diplomatic responses to terrorism." Military preparedness needed improvement in the development of "doctrine, planning, organization, force structure, education, and training" to better combat terrorism, while the USMNF was "not prepared" to deal with the terrorist threat at the time due to "lack of training, staff, organization, and support" specifically for defending against "terror threats."[93]
