In southern Lebanon, a ceasefire can leave a family close enough to watch its home being destroyed, yet unable to return. In September, the Associated Press described residents of Mansouri, displaced to nearby Hanniyeh, watching Israeli drones drop explosives on their village. That distance between a diplomatic announcement and daily life is the proper measure of America’s emerging antiwar politics.

Abdul El-Sayed’s victory in Michigan’s Democratic Senate primary offers those politics an opening. His campaign challenged U.S. support for Israel and connected foreign policy to the use of public money at home. For Lebanon, the consequential question is whether candidates making that argument can eventually change Washington’s decisions on military assistance and regional diplomacy. A primary victory establishes political possibility. Making it useful abroad requires congressional power.

El-Sayed defeated Representative Haley Stevens in August in a contest marked by extraordinary outside spending. Responsible Statecraft reported that the United Democracy Project, the American Israel Public Affairs Committee’s super PAC, spent $30.6 million on the race. El-Sayed argued that Michigan’s tax dollars should support schools, health care, and roads. By tying opposition to Israeli policy to campaign finance and domestic priorities, he gave voters several reasons to challenge the party’s established position.

The result deserves attention because Michigan is a competitive state, and the nomination puts El-Sayed into a general election against Republican Mike Rogers. It does not establish that foreign policy decided the primary. Voters choose candidates for overlapping reasons, and an election result cannot isolate the influence of Gaza, Iran, or donor spending. Nor does a Democratic primary establish what the broader electorate will accept in November.

National polling nevertheless shows why this argument has room to grow. A Pew Research Center survey conducted in March found that 59 percent of U.S. adults considered the decision to use military force against Iran wrong. In Quinnipiac University’s June 24 poll, 60 percent of registered voters said the military action had not been worth it. The same poll found that 48 percent thought Washington was too supportive of Israel, rising to 66 percent among Democrats.

These surveys asked different questions of different populations. They cannot be treated as a single trend line or as endorsements of El-Sayed’s entire platform. They do suggest an electorate more receptive to arguments against escalation than the persistence of U.S. military commitments might imply. The gap between public unease and government action is precisely where an antiwar coalition would have to work.

Lebanon makes the stakes concrete. Reuters reported on September 13 that Israeli and Lebanese representatives were expected to meet in Rome in October to advance a U.S.-brokered security agreement. Israel continued to hold a buffer zone in southern Lebanon. More than 4,300 people had been killed by Israeli strikes since March, according to Lebanon’s Health Ministry, as cited by Reuters. Negotiations remained necessary because earlier rounds had failed to resolve the territorial disputes.

The obstacles extend beyond Washington. Reuters reported on September 10 that Israel said it had destroyed a Hezbollah underground complex at Ali al-Taher. Israel has linked withdrawal to Hezbollah’s disarmament, while Hezbollah has refused to disarm. Those positions expose the central problem of sequencing: Each side can invoke the other’s conduct to defer its own obligations. Civilians bear the cost of that impasse.

An effective American antiwar policy must address this problem without treating Lebanese sovereignty as expendable. Opposing Israeli attacks does not require excusing Hezbollah’s armed autonomy or its decisions to involve Lebanon in regional confrontations. Security for Israeli border communities must also be part of any durable agreement. Washington should pursue arrangements that protect civilians on both sides while strengthening the Lebanese state’s authority, with verifiable obligations for withdrawal and disarmament.

Congress has tools to influence that effort. A Congressional Research Service analysis of military operations explains how lawmakers can restrict funding and set statutory limits, while also describing constitutional disputes and practical obstacles. Legislators seeking restraint should specify which activities may receive money, require reporting on how assistance is used, and press for explicit authorization of sustained hostilities. Restrictions should be drafted to preserve force protection and an orderly withdrawal where necessary.

Passing such measures requires more than adding a few dissenting voices. Binding legislation generally needs agreement in both chambers and presidential approval, or enough votes to override a veto. A new lawmaker can demand recorded votes and expose the costs of existing policy but cannot independently stop weapons deliveries or compel a ceasefire. Campaign promises should be judged against those institutional realities.

The coalition would also need to explain what restraint would fund and support. Congress should pair limits on military assistance with sustained humanitarian funding and oversight of reconstruction support in Lebanon. It should require the administration to report publicly on ceasefire violations and progress toward civilian returns, with sensitive operational details handled separately. These are proposals for making diplomacy accountable, not claims that Washington can dictate every outcome.

There is room for cooperation among lawmakers who disagree on much else. Concern for Palestinian rights can overlap with opposition to open-ended spending and unease about presidential war powers. Such cooperation will be fragile if it depends on agreement about every regional actor. A narrower commitment to limiting escalation and scrutinizing the use of American resources has a better chance of surviving individual campaigns.

Michigan has made that project more plausible. Its value for Lebanon will depend on what follows the election: the appropriations lawmakers support, the conditions they defend, and the diplomatic work they are willing to sustain once attention moves elsewhere. For displaced families, the meaningful result would be a return that lasts. American antiwar politicians should be measured by whether their decisions help make that possible.
