If your talking about the Kiev regime, they were installed not voted in, after a coup d'etat... If your talking about Western governments in general, than maybe they have credibility in terms of representing their own people, but they have none when it comes to meddling in foreign countries. Look what they've done to everything they've touched, Afghanistan, Iraq, Libya... Those were all catastrophes, so zero credibility there.
Same thing can be said about Russians, who love to put the pots that don't belong to them. They had their fun in Afghanistan too, then in Yugoslavia, Chechnya and of course Georgia.
