“We are rather puzzled as to why all of a sudden this issue has emerged,” Gottemoeller said. “It was discussed during the negotiation of the NPT during the late 1960s, the record clearly shows that the United States conveyed at the time that these weapons are not somehow shared with our NATO allies, but in fact remain under the operational control of the United States.”
Gottemoeller added the Soviet Union never mentioned that US deployment of nuclear weapons constituted a violation of the NPT, nor has Russia up until today.
The exact number of US tactical nuclear weapons deployed in Belgium, Italy, Turkey, Germany and the Netherlands is unknown, but the Center for Arms Control and Nonproliferation research group estimates that around 500 warheads are deployed in those countries.
The NPT is an international treaty to prevent the spread of nuclear weapons and technology as well as to promote peaceful uses of nuclear technology.
