American defense experts say the U.S. government needs to closely communicate with Chinese leaders in order to prepare for a state of emergency in North Korea.
A report by the U.S. National Defense Panel -- led by former Defense Secretary William Perry and retired Army General John Abizaid -- says the most probable emergency scenarios would be the breakout of a war or regime collapse.
The independent panel assesses the Pentagon's Quadrennial Defense Review.
The report added there was an increased need to dispatch U.S. troops to South Korea amid heightened tensions on the peninsula.
It added that the stationing of smart weapons was urgent in order to ease nuclear tensions and reduce civilian deaths in case of war.
Citing the U.S. Defense Intelligence Agency, the report said North Korea is concentrating on the development of nuclear weapons and missiles, because it lacks conventional military strength, adding that plans are needed to secure the North's nuclear weapons in case they fall into the hands of terrorists.
The panel also said the North's precise guided missiles and poor cyber community makes it difficult for U.S. defense planners to come up with plan in how to deal with an emergency situation out of Pyongyang.
The panel report added the defense review fails to fully address growing national security threats, including nuclear proliferation by North Korea and Iran, the insurgency in Iraq and the crisis in Ukraine.
The chairman of the House Committee on Armed Services, Howard McKeon, said the U.S. military is facing a high risk, adding that a strong military underwrites all other tools the U.S. has for global influence.
