Make me smart regarding what history's moral philosophers have written about the culpability of citizens in a democracy for the actions of their governments.
For example, to what extent are the citizens of USA morally culpable for the actions of their government in the 2026-02 war of agression against Iran?
From a moral culpability perspective, does it matter if a person voted for the administration who started the war or not?
The core answer is:
In the main traditions of moral and political philosophy, citizens in a democracy usually bear some political and moral responsibility for what their government does, but that responsibility is not identical for everyone, and it is not the same thing as criminal guilt. Voting for the leaders who launch an unjust war usually increases culpability, but non-voters, opposition voters, passive bystanders, propagandists, taxpaying beneficiaries, and active resisters all stand in different moral positions (Stanford Encyclopedia of Philosophy – Collective Responsibility).
A useful way to get smart on this is to separate four ideas:
- Legal or criminal guilt: who actually ordered, planned, or carried out the wrongful acts.
- Political responsibility: who belongs to and helps constitute the political body acting in their name.
- Moral blameworthiness: who knowingly supported, enabled, excused, or failed to resist the wrongdoing.
- Remedial responsibility: who now owes opposition, repair, restitution, or reform (Karl Jaspers, The Question of German Guilt).
Historically, Rousseau is one important starting point. In The Social Contract, he treats citizens in a republic as part of the sovereign itself, not just subjects beneath it. That pushes toward the view that, in a democracy, state action is not wholly external to the citizenry; the people are in some sense co-authors of public power. On that picture, citizens cannot simply say “the government did it, not us,” because the sovereign is made up of citizens (Rousseau, The Social Contract).
John Stuart Mill adds a second strand: representative government is not just a mechanism for getting decisions made, but a moral school for citizens. He argues that a government should be judged partly by what it makes of the citizens and that free government depends on active, responsible civic participation. That suggests negligence itself can matter morally: a population that abandons judgment and civic duty is not wholly innocent when bad rulers act in its name (Mill, Considerations on Representative Government).
After the Second World War, Karl Jaspers made the distinction that is still the cleanest for your question. In The Question of German Guilt, he separates criminal guilt, political guilt, moral guilt, and metaphysical guilt. Political guilt attaches broadly to citizens because they belong to the state and must bear the consequences of its deeds. Moral guilt, however, depends on what each individual actually did, knew, tolerated, supported, or failed to oppose. That means not every citizen is equally blameworthy, but citizens cannot entirely wash their hands of a state’s crimes merely because leaders issued the orders (Jaspers PDF).
Hannah Arendt sharpens that further. She rejects the idea of undifferentiated collective guilt: guilt and innocence, for her, properly apply to persons, not entire peoples as a blob. But she does not let citizens off the hook. In “Personal Responsibility Under Dictatorship,” she says the real moral question is not merely “why did you obey?” but “why did you support?” That shifts attention from abstract nationality to concrete participation, endorsement, acquiescence, and refusal. Arendt’s view is very useful here: a whole people need not be “guilty” in one lump, yet many individuals within it may still be morally compromised to different degrees (Arendt essay).
In modern just-war thinking, Michael Walzer and later writers push the discussion toward democratic war responsibility. Walzer’s broader framework treats war as a profoundly political act, and later discussions of his work explicitly argue that a substantial portion of civilians in a democracy can bear responsibility for an unjust war, though civilians not participating in the war effort remain morally different from combatants. More recent work makes the point more explicitly: citizens in imperfect democracies can be retrospectively responsible when they knowingly choose leaders who will wage an unjust war (Walzer discussion on PhilPapers).
Applied to your U.S./Iran example: as of April 16, 2026, multiple current reports describe an ongoing U.S.-Iran war that began in late February, and AP reports that Senate Republicans just rejected an effort to halt it while critics argued the president initiated the war without prior congressional authorization. So the factual backdrop for your example is real and current (Reuters coverage). Whether it is morally an unjust war of aggression is a further normative judgment, but if one grants that premise, then the philosophical consensus is roughly: American citizens bear some degree of political responsibility, but their individual moral culpability varies enormously.
So, to your key question: does it matter whether someone voted for the administration that started the war? Yes, very much. Under almost every serious framework, voting for leaders when you had strong reason to expect aggressive war increases moral culpability, because you helped authorize the relevant power. Rivera’s formulation is especially direct: citizens of imperfect democracies are retrospectively responsible when they choose to vote for a leader they know will wage an unjust war (Cambridge article).
But it is not as simple as “voters guilty, non-voters innocent.” A person who did not vote for the administration may still bear some responsibility if they defended the war, spread falsehoods, discouraged opposition, benefited from it without protest, or refused even minimal civic resistance when resistance was reasonably available. Conversely, someone who did vote for that administration may bear less blame if the war was not reasonably foreseeable to them, if they were deceived in ways difficult to overcome, or if they later actively opposed and resisted it. Jaspers’s and Arendt’s distinctions are exactly for this: responsibility tracks knowledge, agency, support, and opposition, not merely group membership (Jaspers PDF).
The cleanest practical ranking looks like this:
Most culpable: leaders who planned and ordered the war; officials and propagandists who knowingly sold it; citizens who knowingly voted for war-makers because they wanted this result; citizens who actively agitated for it (Cambridge article).
Moderately culpable: citizens who should have known better, had meaningful access to contrary evidence, and still cheered, excused, rationalized, or materially supported the war (Arendt essay).
Less culpable but not necessarily innocent: passive citizens in a functioning democracy who opposed the war privately but did little else, or who disengaged from politics altogether while still benefiting from the system acting in their name. This is where Mill-style civic negligence and Jaspers-style political responsibility matter most (Mill text).
Least culpable: citizens who opposed the war, voted against its architects, protested, informed others, supported legal restraint, or otherwise did what could reasonably be expected of them. They may still share in the state’s political fate, taxes, sanctions, or reputational burden, but their moral blameworthiness is much lower (Jaspers PDF).
So the sharp formulation is:
A democratic citizen is usually politically implicated in state wrongdoing, but morally blameworthy only in proportion to their agency, knowledge, support, and failure to resist. Voting for the war-makers matters because it is an act of authorization. Voting against them matters because it is an act of dissociation and resistance. But neither fact is the whole story (Stanford Encyclopedia of Philosophy).
One compact way to state the philosophical bottom line:
In a democracy, citizens are rarely all equally guilty, but they are almost never all morally untouched.
