"...
he was replaced
..."
He was impeached in an unconstitutional manner. Already discussed it the other day. There's no such procedure in Ukrainian constitution as "replacement". You made it up.
no coup
Yes, there was a coup. Unlawful, violent seizure of power from a government. That's pretty much the definition of a coup.
no arms
LOL.
no US causing it
Maybe they didn't cause it, but they certainly backed and funded various organisations that held an anti-Russian sentiment
no illegality
President was impeached in a manner that breached the Ukrainian constitution = illegal.
