US Defense secretary warns Iran and North Korea

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. The new policy would not apply tostates like North Korea and Iran because of their refusal to cooperatewith the international community on nonproliferation standards.
"All options are on the table when it comes to countries in that category," Gates said.
