Pentagon officials say the only way to stop North Korea's nuclear programme would be a ground invasion that would disarm the rogue nation of its power.
According to reports, the claim came after two US congressmen asked for an evaluation of the human cost of a war with North Korea as tensions heighten between the two nuclear powerhouses.
"The only way to 'locate and destroy with complete certainty all components of North Korea's nuclear weapons programmes is through a ground invasion," Rear Admiral Michael Dumont said in a statement on behalf of the Joint Chiefs of Staff.
Rear Admiral Dumont added while calculating the cost of human life would be difficult he said there is a possibility that chemical and biological weapons could be used by North Korea in a war.
There are no good military options for North Korea - congressmen
Following that bleak assessment by the Joint Chiefs of Staff, Congressman Ted Lieu released a statement alongside other lawmakers and war veterans to warn of the dangers of war.
"The Joint Chiefs of Staff has now confirmed that the only way to destroy North Korea's nuclear arsenal is through a ground invasion," the statement reads.
"That is deeply disturbing and could result in hundreds of thousands, or even millions of deaths in just the first few days of fighting.
"As Veterans, we have defended this nation in war and we remain committed to this country's security. We also understand that entering into a protracted and massive ground war with North Korea would be disastrous for US troops and our allies."
