The West destabilized Ukraine and organized, facilitated the coup and thus facilitated the overthrowing of Yanukovych.
The demonstrations which began in Kyiv in November 2013 – called "Maidan", or "Euromaidan" – were not provoked from outside but were a result of the Ukrainian people's frustration with former President Yanukovych's last minute U-turn when, after seven years of negotiation, he refused to sign the EU–Ukraine Association Agreement and halted progress towards Ukraine's closer relationship with the EU as a result of Russian pressure. The protesters' demands included constitutional reform, a stronger role for parliament, formation of a government of national unity, an end to corruption, early presidential elections and an end to violence http://bit.ly/2ftv6iT.
Far from destabilising Ukraine or using it as a tool of aggression, the EU and its Member States have been deeply engaged in seeking a solution to the crisis brought about by Russia's subsequent military intervention in the East of the country. France and Germany are, together with Ukraine and Russia, the four members of the Normandy contact group tasked with resolving the situation in the East of Ukraine. EU High Representative Federica Mogherini has reaffirmed many times that the implementation by all sides of the Minsk agreements, signed to bring to an end the conflict in the East, is an absolute priority.
The EU is also supporting, not destabilising Ukraine, through one of the most ambitious reform programmes it has ever undertaken. The provisional application of the Deep and Comprehensive Free Trade Area offers Ukraine privileged access to a market of over 500 million consumers. The EU has provided long term loans to Ukraine to help stabilise its economy, as well as substantial budget support, technical assistance and loans to SME businesses. The EU is both currently and historically the biggest international donor to Ukraine, and has proposed an overall support package of at least €11bn to help stabilise the economic and financial situation.
