"On December 7, 1993, Secretary of Defense Les Aspin announced that the United States was adding a military dimension to its fight to prevent the spread of weapons of mass destruction (WMD). The new program, called the Counter-Proliferation Initiative (CPI), provides funding to prepare for combating foes with nuclear, biological, and chemical (NBC) and missile weapons on future battlefields, improves monitoring for locating rival NBC/missile programs, improves theater defenses, and develops weapons capable of penetrating and destroying underground facilities. U.S. efforts will include a diplomatic offensive to persuade U.S. allies to take similar counter-proliferation steps. The central thrust of the CPI is to prepare U.S. and allied forces for dealing with future enemies on the battlefield who are armed with weapons of mass destruction. An important secondary thrust of the CPI is to provide the Commander-in-Chief with the tools to disarm an adversary unilaterally if necessary, before the adversary can initiate the use of WMD in situations where we are on a collision course with such an enemy and no alternative course seems feasible."
