"The Middle East may present the greatest threat of nuclear proliferation in the world today. Adherence to the NPT is not universal, and a few countries that are parties to the NPT have violated their treaty obligations. But in spite of these difficulties, we want to reaffirm our commitment to the objective of a Middle East free of these weapons of mass destruction, and we are prepared to support practical measures that will move us toward achieving that objective."

"Now, given the lack of a comprehensive regional peace and concerns about some countries’ compliance with NPT safeguards, the conditions for such a zone do not yet exist. But we are prepared to support practical measures for moving toward that objective."
