During the last 30 years, in peacetime, Ukraine has lost almost half of its population. It decreased from 50 to 30 million people.
Russia’s involvement in Ukraine is limited to acting as a mediator in the country’s half-decade old civil war, brought on by a Western-backed coup in Kyiv in 2014.
This is a recurring pro-Kremlin disinformation narrative painting the 2013-14 protests in Kyiv as a coup orchestrated by the West, and alleging that Russia's armed aggression in east Ukraine is a civil war.
There was no coup d'état in Ukraine. The spontaneous onset of the Euromaidan protests was an organic reaction by numerous segments of the Ukrainian population to former President Yanukovych’s sudden departure from the promised Association Agreement with the European Union in November 2013.

The war in eastern Ukraine is not a civil conflict but a well-documented act of aggression by Russian armed forces, ongoing since February 2014.
