This Is How America Would Wage a Nuclear War Against North Korea
If Trump’s words are taken at face value and a nuclear first strike is a real option that he is considering, the U.S. Air Force’s fleet of twenty Northrop B-2 Spirit stealth bombers will likely have to shoulder the burden. “We haven't had tactical nukes in the fleet since the Bush I administration, so no first strike will come from the sea,” James R. Holmes, professor of strategy at the U.S. Naval War College—speaking in a personal capacity—told The National Interest. “An ICBM or SLBM strike could be misinterpreted by China and Russia as against them, so that's probably out as well. My guess would be that USAF bombers, probably B-2s, would carry out the mission.”
As for conventional options, the B-2 can carry a pair of 30,000 pound GBU-57A/B Massive Ordnance Penetrator bombs, but the U.S. Air Force only has a handful of those weapons in its inventory. It is not clear if there are enough GBU-57s available to substantially damage the North Korean nuclear program, let alone destroy it.
“On the conventional side, there are bunker-busting munitions. We're back to the USAF as the primary executor of the operation, with THAAD and Aegis ships providing the defense against missile launches,” Holmes said. “How effective bunker busters would be would depend on how many sites need to be struck, how deep and extensive the bunkers are, and whether we could concentrate enough fire on them to do the job.”
Davenport agreed that the United States has conventional military options—but there is no guarantee of success. Moreover, North Korea could retaliate with its road-mobile ballistic missiles, which are designed to ride out a first strike by dispersing.
“The United States has non-nuclear options in the region for targeting North Korea’s nuclear assets, such as airstrikes and cruise missiles,” Davenport said. “But while a conventional strike would be less devastating, there is still no guarantee that the United States would hit all of Korea’s nuclear assets. The U.S. has fewer intelligence options at its disposal in North Korea, and Pyongyang has mobile nuclear-capable missiles that are more difficult to track.”
Even if Trump were to resort to the nuclear option, there are questions as to how effective such an attack would be. “I guess the answer depends on how you define effective,” Holmes said. “One imagines we could take out the program with nukes, but at what cost? Even apart from the obvious loss of life and material damage, you're talking about nuking a country that is centrally located among American allies and prospective foes.”
In fact, the collateral damage to the United States’ network of alliances and Washington’s standing in the world could be catastrophic. “There would be a very real prospect of breaking our alliances with Japan and South Korea and assuring permanent enmity from China and Russia,” Holmes said. “We would also place our position as guarantor of the international order in jeopardy. As you suggest, it's hard for an international pariah to lead by example. So my answer would be: a first strike wouldn't be effective even if it worked. The returns don't justify the enormous costs.”
Another factor to consider is that a military attack that is intended to disarm North Korea’s nuclear forces might actually prompt a nuclear retaliation. “If the North Korean regime thought is nuclear deterrent was at risk, either from a nuclear or conventional strike, Pyongyang might miscalculate and launch its own nuclear weapons,” Davenport said. “A nuclear exchange of any size would have devastating regional consequences. Even a strike targeted solely at taking out North Korea’s intercontinental ballistic missiles runs the risk of being misinterpreted by Pyongyang as part of a larger military operation.”
Indeed, as former director of national intelligence, retired Air Force Lt. Gen. James Clapper told CNN, North Korea is looking at the world in strict realist terms. Pyongyang—from its vantage point—is surrounded by enemies that are overwhelmingly more powerful than it is. The Kim regime’s only trump card against those foes are their nuclear weapons. Because the survival of the Kim regime is dependent on their nuclear capability, Pyongyang will never give up those weapons under any circumstances. Thus, America’s best response is containment and deterrence. “We need to have dialogue with them,” Clapper told CNN. “But accept the fact they are a nuclear power."
