Yes, like i said after Ukraine became anti-russian.
Throwing out an elected government through paid nationalist elements, who then systematically began anti-Russian policies against eastern Ukrainian. A part of Ukraine that was/is overwhenmingly pro-Russian and has Russian majority provinces, that voted for the government that was removed from power by foreign interference.
Ukraine did not "throw out an elected government".
The Ukrainan president Yanukovich signed an agreement with Russia (possibly after bribing)
when the Ukrainan government was in final stages of an agreement with the EU.
When Ukraine started preparing an impeachment against the President, he escaped to Russia, stealing 30 billion dollars in the process.
Since he was unable to perform his duty Ukraine selected an acting president.
The Ukrainan Constitution allows for an acting President when the President is unable to perform his/her duty due to medical conditions. The situation where the President was refusing to do his/her duty was not foreseen. This ambiguous situation lasted for a year, until the next planned Presidential election happened.
Yanukovich formally was president until the end of his term, but would have been impeached.
He was later tried in absentio and convicted as a traitor.
Even before Yanukovich left, the operation to annex Crimea had started.
The Donbass rebellion was started within days of Yanukovich leaving and all the leaders were Russian citizens with support by the Russian Army disguised as volunteers.
Russia officially invaded 4 months later in August 2014.
The foreign interference was present, and mostly Russian.
