The greatest crime since World War II has been U.S. foreign policy.

In this remark, Clark frames U.S. actions abroad not as a series of debatable strategic choices but as a moral and legal catastrophe—“crime” on a scale comparable to the era’s worst atrocities. The superlative (“greatest”) signals a sweeping indictment: he is collapsing diverse interventions, wars, covert operations, and support for repressive regimes into a single historical judgment about harm inflicted on civilian populations and the erosion of international law. The quote’s force depends on deliberate provocation: it challenges post‑1945 narratives of American leadership by asserting that the principal source of large-scale wrongdoing has been policy made in Washington, not merely isolated abuses or mistakes.
