"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."

But we are prepared to support practical measures for moving toward that objective."
