US Midterms as a Referendum on Foreign Policy

US midterm elections are often framed as a verdict on the sitting president. This year, analysts say the ballot box is also delivering a verdict on America’s long-term foreign policy course. Trade wars, military alliances, foreign aid and global supply chains may look distant, but they reach ordinary Americans through jobs, prices and the fortunes of their communities.

The link is not new, but it has grown sharper. After Donald Trump’s 2016 win, his MAGA base made cutting foreign spending, raising tariffs, avoiding new wars and withdrawing from Afghanistan central demands. Trump’s approval ratings were still high in 2019, suggesting the pitch retains lasting appeal with part of the electorate. Behind it sits a question that often gets blurred: is America’s problem too little wealth, or how that wealth is distributed?

Where foreign spending actually goes

Trump repeatedly says the US sends vast sums abroad. That is true. But the money does not all leave the country. Most spending on foreign wars flows to the domestic defense industry. A large share of funding for international organizations and global NGOs pays US institutions and personnel. Cutting tariffs to help domestic firms is essentially granting tariff-free access to US companies’ overseas contract factories, so the beneficiaries are still American firms. The issue is not the size of the pie but how it is sliced.

Decades of intervention and expansion have distorted the rewards in the US economy. Units involved in foreign intervention and expansion capture a growing share of wealth, while those focused on domestic interests see little return. Trump himself has said multinationals use low tax rates to move factories and production lines out of the US, earning huge profits while Americans lose jobs, and that the military-industrial complex uses expansion to earn vast sums while bankrupting the US Treasury.

Trump’s fix: charge for influence

Trump’s answer is not to adjust distribution. He argues the US spends too much in places that yield no return, and that Washington should use its leverage to collect money and expand returns. He uses tariffs and disrupted trade ties as leverage to demand huge investment and large purchases of US goods. He uses troop withdrawals and threats to end military protection as leverage to push allies to buy expensive US weapons and pay more for hosting US forces. The approach turns foreign policy into a tool for extracting gains from the existing system.

That may produce some short-term book gains, but it does not touch the root of the distribution problem. It may instead raise international tensions, hurt US firms’ overseas markets and loosen the alliance system. In the midterms, the parties’ split over foreign policy — continued traditional internationalism or a shift to transactional bilateralism — became a major dimension of voter choice.

What the ballots are really saying

Supporters of Trump’s approach see the midterms as a reaffirmation of “America First,” with voters demanding an end to paying for the world and resources kept at home. Critics say the approach reduces a complex distribution problem to “spending too much abroad,” and may weaken US global influence without helping ordinary workers. Other observers argue midterm results mostly reflect local issues and candidate personalities, and that foreign policy’s weight is overstated.

Whichever reading is right, one fact is clear: the tie between US foreign policy and domestic economic distribution is becoming harder to miss. Voters’ choices in the midterms are feedback on specific policies and a statement on a fundamental question — what role should America play in the world. As the costs and benefits of foreign intervention become more unbalanced at home, electoral politics will inevitably pull foreign policy into the fight.

This election may not change America’s diplomatic direction overnight. But it reminds policymakers that a foreign policy without broad domestic buy-in is hard to sustain. How to balance a global role with domestic well-being remains an open question in US politics.
