But what are the military options available to the United States should it come to war? Arms control advocates note that a preventative nuclear first strike would be a gross violation of international law. “Talk of targeting North Korea with nuclear weapons is delusional and should be off the table,” Kelsey Davenport, director for nonproliferation policy at the Arms Control Association, told The National Interest. “In addition to the gross illegality of a preventative nuclear strike, the humanitarian, economic and environmental consequences would be devastating—and not just contained within North Korea’s borders. Washington would be putting U.S. allies at serious risk, both from the fallout, but also from a North Korean counter attack.”
The standoff between the United States and North Korea continues to escalate with neither side willing to back down.
With each passing day, the possibility of open warfare breaking out seems to increase as each side ups the ante. Indeed, President Donald Trump has ratcheted up his rhetoric in recent days—seemingly threatening to launch a nuclear first strike against North Korea.
“North Korea best not make any more threats to the United States,” Trump told reporters at his golf club in Bedminster, New Jersey. “They will be met with fire and fury like the world has never seen. He has been very threatening beyond a normal state and as I said they will be met with fire and fury and frankly power the likes of which this world has never seen before.”
Just hours later, Kim Jong-un’s regime in Pyongyang threatened to preemptively strike at American forces given even a “slight sign of the U.S. provocation.” That, according to the North Korean statement, would include a “beheading operation” such as a special operations forces raid aimed at assassinating Kim.
“The U.S. should remembered, however, that once there observed a sign of action for ‘preventive war’ from the U.S., the army of the DPRK will turn the U.S. mainland into the theatre of a nuclear war before the inviolable land of the DPRK turns into the one,” reads a North Korean Foreign Ministry statement. “We do not hide that we already have in full readiness the diversified strategic nuclear strike means which have the U.S. mainland in our striking range.”
Meanwhile, Defense Secretary Jim Mattis—while taking a more measured tone—issued a statement on August 9 warning North Korea that it must give up its nuclear weapons. “The DPRK [Democratic People’s Republic of Korea] must choose to stop isolating itself and stand down its pursuit of nuclear weapons,” Mattis said. “The DPRK should cease any consideration of actions that would lead to the end of its regime and the destruction of its people.”
Mattis also warned that the United States would continue to maintain overwhelming nuclear superiority over Pyongyang. “While our State Department is making every effort to resolve this global threat through diplomatic means, it must be noted that the combined allied militaries now possess the most precise, rehearsed and robust defensive and offensive capabilities on Earth,” Mattis said. “The DPRK regime’s actions will continue to be grossly overmatched by ours and would lose any arms race or conflict it initiates.”
If tensions with North Korea boil over into open warfare—or if Trump decides to launch a preemptive strike—there are military options available to the United States. However, the collateral damage that might be wrought onto South Korea and Japan could be devastating.
“We would not necessarily need to resort to a nuclear strike,” one retired Defense Department official told The National Interest. “We have conventional capabilities and capacity to take out many of the threats we are most concerned with. It wouldn’t be easy, of course.”
Another high-ranking former senior defense official said that North Korea is a complex, multi-dimensional problem. It is not an issue that can be solved by the military or even the United States by itself. All of the stakeholders in the Western Pacific including Japan, South Korea, China, Russia and United States have to be part of the equation. “Endorsing Japan and South Korea seeking their own nuclear deterrent force may get China’s attention,” the former senior defense official said. “There are many such options available and that needs to be played out before resorting to the military option is the best way ahead.
