A coup only gets to rule what they can physically grab by force. There isnt some nutty right to rule everything the old government had because you seized the Capitol. The eastern areas have the same right to grab an area that the people who grabbed Kiev had.
Sorry, Ukraine has had internationally recognized elections since the “coup”. Even Russia recognized the election of Poroshenko. You’re barking up the wrong tree there, FRiend.
Sorry, but the east has as much natural right to separate from the coup, as the coup did to gain power by force. And big surprise that the nations that funded the coup endorsed it.
The war didn’t start until the maidan bunch organized into militias and moved east to consolidate power. Screw them.
