No, a mob did not depose him. He was impeached strictly according to the Ukraine's constitution by the Ukrainian Parliament.
A large number of citizens protested his unilateral actions and his amassing or power. Those protests turned ugly and the security forces began killing the protestors.
But you know what, those protestors did not turn back. Watch this intense video of protesting citizens being gunned down...but others coming right up to take their place ad continue to advance. It is long, but worth watching. That was a group of dedicated citizens who knew the true value of liberty and their rights.
Would that our own people saw things so clearly.
When it was clear that the protestors were not going to stop and would reach the Government buildings including the Presidential buildings...the President fled. Then, as I said, the Parliament of Ukraine, strictly according to their constitution, impeached him and removed him from power.
If you are going to try and stand on the legality of his election, then you cannot have it both ways. he was also legally and constitutionally impeached.
2014 Ukraine Crisis - Part I: Maidan Protests
2014 Ukraine Crisis - Part II: Russia takes the Crimea
Being duly elected goes out the window the moment there are kidnappings, tortures and dictatorial laws. Causing 80 dead - that’s even more special, that puts him in the Mugabe/African despot legitimacy category.
He’s not that popular in E. Ukraine or Crimea, for example after he fled Kiev, there were no scenes of outrage and support for him in the East. He’s corrupt and they tolerated him because he’s one of theirs, it goes no further than that. The fact that he fled to Russia, not his support base, is also telling.
Up till now, one of the few things that Ukrainians have agreed on, it is to stay as one country. This could change in light of the recent crisis, I don’t know, but the point is, it should be Ukrainians who decide if they should split up, not the outsiders.
