Based on the supplied reporting, the claim that the phrase functions as a shorthand for Nazi-style collective reprisal is widely circulated and used rhetorically, and commentators tie it to Lidice and other Nazi reprisals—yet the sources provided do not include archival proof that the exact English wording “One of ours, all of yours” was an official Nazi slogan in 1942; the evidence in these excerpts is inferential and rhetorical rather than documentary. To move from plausible association to verified etymology would require primary-source confirmation—wartime orders, propaganda texts, or credible historian citations—not present in the materials supplied here, and that absence should temper absolutist claims even as the phrase’s invocation remains politically and morally potent.
