This Is How Much a Major War With North Korea Would Cost Us

President Donald Trump and Kim Jong Un closed out their second summit on Feb. 28 without reaching an agreement on the key issue of denuclearization of North Korea. The two leaders began their summit in Hanoi, Vietnam, just a day earlier. Prior to their first summit, The New York Times reported that officials on both sides scrambled to work out issues that have dogged relations for decades. But the hope was that the summits would lead to the official end of the Korean War, and possibly more.

Both nations have clearly defined their agendas. The U.S. wants to see North Korea eliminate its nuclear weapons program, while North Korea wants American nukes out of South Korea. These are difficult positions to reconcile, but the alternative could lead to war.

Despite North Korea’s small size, a military conflict would not be cheap. Click through to see how much a war with North Korea could cost the U.S., and how it measures up to the cost of America’s previous wars.

Potential Cost of War With North Korea

How much would World War III with North Korea cost the U.S.? First off, it would entail enormous indirect costs beyond direct military expenditures, the most severe being the economic losses and disruption due to South Korea waging war against its neighbor.

South Korea is one of the largest producers of electronics goods in the world. If the country had to shift its economy toward war — and away from electronics production — many companies would be forced to find alternative suppliers, which are few.

One result would be more expensive smartphones, tablets and other devices as companies roll back manufacturing in response to the electronics shortage. More broadly, war against North Korea would destabilize global trade as South Korea is home to major container ports and manufacturing industries on which much of the world is dependent.

A quick war could limit the amount of economic disruption the U.S. would face, but that doesn’t mean war with North Korea would be cheap. Based on military budgets, expenditures and costs of previous conflicts, the cost of a war with North Korea could be the most expensive war in U.S. history.

In theory, war with North Korea should be similar to war in Iraq, since the U.S. would be fighting a nation-state with a professional army. And like Iraq, when the army is defeated, the population might still resist. The war in Iraq exceeded $800 billion, while total post-9/11 operations cost more than $1 trillion.

If war were contained to North Korea, the cost of war between the U.S. and North Korea might fall between $800 billion and $1 trillion. If war spreads beyond North Korea, it could easily escalate into the trillions — and significantly add to America’s staggering national debt.

Cost of Past U.S. Wars and Military Campaigns

It is difficult to overstate the economic cost of the Sept. 11 attacks and subsequent War on Terror. The Department of Defense’s requested budget for 2017 was just under $600 billion, but its request for 2010 — during the middle of the War on Terror — was $784 billion. That amount is higher than defense spending under President Ronald Reagan during the feverish final years of the Cold War.

According to a December 2014 report from the Congressional Research Service, Congress approved a total of $1.6 trillion for war operations since the Sept. 11 terrorist attacks. The cost breakdown is as follows:

  • War in Afghanistan: $686 billion (43 percent) for Operation Enduring Freedom for Afghanistan and other counterterror operations received
  • War in Iraq: $815 billion (51 percent) for Operation Iraqi Freedom/Operation New Dawn
  • Operation Noble Eagle: $27 billion (2 percent) for providing enhanced security at military bases
  • Other: $81 billion (5 percent) for war-designated funding not considered directly related to the Afghanistan or Iraq wars

But to really grasp how expensive war is for the U.S., just look at what it costs to fund the average soldier. According to an analysis of the fiscal year 2014 defense budget from the Center for Strategic and Budgetary Assessments, the cost per single service member deployed to Afghanistan was $2.1 million. A report by Harvard University’s Kennedy School of Government calculated that the wars in Iraq and Afghanistan have cost every American household roughly $75,000 each.

The cost of the Iraq War and War in Afghanistan far outstrips the cost of most recent conflicts involving the U.S. Adjusting for inflation, only World War II exceeds the military expenditure of the War on Terror. Here’s a closer look at the military cost of America’s past wars in constant fiscal year 2011 dollars:

  • American War of Independence: $2.407 billion
  • War of 1812: $1.553 billion
  • Mexican-American War: $2.376 billion
  • Civil War (Union): $59.631 billion
  • Civil War (Confederacy): $20.111 billion
  • Spanish-American War: $9.034 billion
  • World War I: $334 billion
  • World War II: $4.104 trillion
  • Korean War: $341 billion
  • Vietnam War: $738 billion
  • Persian Gulf War: $102 billion
  • Iraq War: $784 billion
  • War in Afghanistan and other: $321 billion
  • Total Post-9/11 Operations: $1.147 trillion

Cost of U.S. Defense Budget

The fiscal year 2017 budget asked for a total of $590.5 billion for the Department of Defense, including $523.9 billion for the base discretionary budget, $7.8 billion in mandatory spending and $58.8 billion in supplemental funding for ongoing Overseas Contingency Operations, according to CSBA’s fiscal year 2017 budget analysis.

Procurement

The base budget request for procurement funding — which consists of acquiring goods and services for the country’s three military branches — was $102.5 billion, with the total defense budget adding up to $112.1 billion. The OCO account requested $9.5 billion for procurement. Here’s the cost of procurement by military service branch:

  • Air Force: $43.9 billion
  • Army: $18.1 billion
  • Navy: $44.8 billion
  • Defense-wide: $5.3 billion

Research, Development, Test and Evaluation Funding

According to the CSBA’s analysis of the fiscal year 2017 defense budget, $71.8 billion was requested for research, development, test and evaluation. Here’s a closer look at the cost breakdown:

  • Air Force: $28.1 billion
  • Army: $7.6 billion
  • Navy and Marine Corps: $17.3 billion
  • DOD-wide: $18.6 billion

Operation and Maintenance

Operation and maintenance costs constitute a large part of the U.S. defense budget. Over the years, operation and maintenance costs have grown, putting military services under budgetary pressure.

The base budget for operation and maintenance funding requested was $205.9 billion for fiscal year 2017, while on top of that, OCO accounted for another $45 billion. Take a look at the operation and maintenance budget broken down by service branch:

  • Air Force: $57.2 billion
  • Army: $63.3 billion
  • Marine Corps: $7.5 billion
  • Navy: $47.6 billion
  • DOD-wide: $75.3 billion

Funding for operating forces — one of four activities that comprise operation and maintenance — made up the greatest share of overall operation and maintenance funding requested for fiscal year 2017. Operating forces includes funding for day-to-day ground, air and ship operations, combat installations, combat support elements and efforts to train and support the readiness of combat elements.

Military Personnel

The fiscal year 2017 budget requested $135.5 billion for discretionary funding for military personnel in the base budget. In terms of total defense budget, the military personnel budget was $138.8 billion. By service branch, the requested military personnel budget breakdown is:

  • Air Force: $35.2 billion
  • Army: $57.5 billion
  • Navy and Marine Corps: $46.1 billion

Military Construction and Family Housing

Another major defense expenditure, though far smaller, is the cost of military construction and family housing. The total amount requested for fiscal year 2017 was $7.4 billion, made up of $6.1 billion for base budget military construction and $1.3 billion for family housing.

Cost of America’s Arsenal

The U.S. boasts the most advanced military in the world, and that means its arsenal is not cheap. Procurement of weapons, vehicles and other tools of war are major military expenditures.

Aircraft

The cost of combat aircraft constituted the largest share of procurement spending, 13.24 percent, behind only classified programs at 14.9 percent. The cost of aircraft modification is a separate category and accounted for about 7 percent, which was higher than the share of procurement spending set aside for missiles.

The Navy and the Air Force had the largest procurement budgets for aircraft. The Navy’s procurement request for aircraft was $77.3 billion, and the Air Force’s request was $78.1 billion. The aircraft procurement budget for the Army was much lower at $19.6 billion. However, it still accounted for more than a fifth of its procurement budget.

Ships

Ranking behind combat aircraft, warships accounted for the third-greatest share of procurement spending, roughly 12.5 percent.

According to Future Years Defense Program projections, the Navy intends to shell out more than $85 billion on shipbuilding in the coming years. Some of the biggest Navy shipbuilding projects include the Virginia-class submarine program ($28.6 billion), DDG-51 Arleigh Burke-class destroyer ($19.3 billion) and its carrier replacement program ($12.4 billion).

Missiles

The Army’s budget for missile procurement was $8.8 billion, while the Air Force’s was $9 billion. Despite being in the billions, the cost of individual missiles isn’t too bad. However, when they are considered as part of a larger weapons system, the true cost becomes more apparent.

Land Vehicles

The days of massive tank battles might be something of the past, but the U.S. still employs various types of combat vehicles.

The Army’s procurement budget for wheeled and tracked combat vehicles was $14 billion. One of the Army’s biggest vehicle procurement programs is the Joint Light Tactical vehicle, intended to be the ultimate, all-terrain ground vehicle of the future. The budget for it was $3.9 billion, according to the FYDP.
