US Defense Secretary Robert Gates said Tuesday that unprecedentedlimits being placed on the US nuclear arsenal will not weaken USdefenses and will send a "strong message" to Iran and North Korea to"play by the rules."Under the plan, the United States would narrow the circumstances underwhich a nuclear weapon would be used.
