Acting due to a change of government is not the prerogative of another state. Putin is within his rights not to recognise that government and to grant asylum to former president Yanukovych but not to take action within the Ukraine to change the situation.  The coup however was not a coup but an abdication. “Yanukovych has lost his legitimacy as he abdicated his responsibilities. As you know, he left Ukraine – or left Kyiv, and he has left a vacuum of leadership.” It was therefore Yanukovych who essentially decided that he was no longer in charge by leaving Kiev and not making any statements for several days.
