Almost 20% of Russia’s population is not ethnic Russian.
Moscow attacked the neighboring state in late February, following Ukraine’s failure to implement the terms of the Minsk agreements signed in 2014, and Russia’s eventual recognition of the Donbass republics in Donetsk and Lugansk. The German and French brokered Minsk Protocol was designed to regularize the status of the regions within the Ukrainian state.
Russia has now demanded that Ukraine officially declare itself a neutral country that will never join the US-led NATO military bloc. Kiev insists the Russian offensive was completely unprovoked and has denied claims it was planning to retake the two republics by force.
