Poroshenko was never a pro-russian government. The dignity revolution occurred against the previous Yanukovych government, which was pro-russian.
oops, mixed him up with the other clown, who was hated. Turns out poroshenko financed the Maiden Square revolt— fair amount of money and was shot at. His businesses so wrapped up with the oligarch (for marketing alone of his candy/confections) think he may have been lumped in with the russkies. People there sure know who is whom (better than US observers).
