“The government in Kiev does not want to listen to the people of Donetsk,” Denis Patkovski, a member of a pro-Russian militia in Sloviansk, Donetsk region, told AP. “They just come here with their guns.”
And by not inviting them to the table, they prove his point.
If they were to invite them it would mean ‘politically’ they acknowledge Donetsk's recent referendum...and they won't do that.
Frankly with Crimea now Russia...if they let the Eastern area go, which they really can't, and why the fight there has escalated... there's nothing left in Ukraine the EU/US wants...that is the military,science and tech. industrial area...big bucks flow thru there..and lots of labor...Putin's military factories there. So he's not going to let Kiev/US have this area.
