The US backed the coup in Ukraine in 2014.
Russia has not interfered in the internal affairs of the EU countries or other countries in the world and does not want to interfere. This is the most important difference from the USA and its allies, who, for example, backed the coup in Ukraine in February 2014.
It was not the United States, but Russia that triggered the military conflict in Ukraine.
As for Ukraine, there was no coup d’état in 2014. The spontaneous onset of massive Euromaidan protests was a reaction of the Ukrainian population to the sudden departure of President Yanukovych from the Association Agreement with the European Union and to the brutal dispersal of student protest actions on 30 November 2013.
