Furthermore, have you considered that the west has been interfering and manipulating Ukrainian politics which culminated in a coup against the democratically elected government in 2014?

How much has that weighted and how much the pre-2014 government was legitimate. I'm open to the possibility that yes, the country governance could have been stolen from the people by the west. But also it's totally makes sense to have a wide willingness to join the EU for economic reasons. And to have a willingness to join NATO after the 2008 Russo-Georgian War. Both would be completely legitimate.

The Russian government has been trying to manipulate Ukraine very strongly also so it's difficult to tell if the governments wanting join the west was illegitimate.
