How we got here
The CSIS study, conducted in Washington, synthesizes casualty figures from American and British estimates and other sources, noting Moscow undercounts its dead and Kyiv does not publish full figures. The war began in February 2022, with fighting widening into the southern and eastern fronts and escalating drone and missile campaigns, including strikes on Kyiv that have wounded and killed civilians.
