Based on my research, the claim that "Two million Ukrainian men are dead or missing" is false.

Reasoning:

• The ~2 million figure refers to combined Russian and Ukrainian military casualties (both sides together), not Ukrainian casualties alone¹. A study by the Center for Strategic and International Studies (CSIS) estimated that Russia has suffered approximately 1.2 million casualties and Ukraine about 500,000–600,000 casualties, with the combined total potentially reaching 2 million by spring 2026¹.
• The 2 million figure includes killed, wounded, AND missing, not just dead or missing. The claim incorrectly narrows this to only "dead or missing"¹².
• Ukrainian military casualties specifically are estimated at 500,000–600,000 total (killed + wounded + missing), with fatalities estimated between 100,000–140,000 according to one analysis², or 55,000 killed according to President Zelenskyy's February 2026 statement³.
• The most rigorously documented figures for Ukrainian fighters show 91,559 killed and 95,165 missing (186,724 dead or missing total) as of April 2026, tracked by name through the UALosses project⁴. These figures, while likely incomplete, are far below 2 million.
• The claim appears to be a misrepresentation of combined casualty data, attributing the total losses of both sides to Ukrainian men only, and conflating total casualties (including wounded) with deaths and missing persons.
