"Brenus, if I was a Romanian I would want as many NATO troops in my country as possible" You might, but you can't expect Russia not to see it as a menace at her door.
Then you guys, are telling that Putin is a mafia boss. You, guys, are telling that Russia is the enemy. So, PVC, if you were a Russian, wouldn't worry to see troops in a country that never miss the occasion to attack you? Wouldn't worry to see a power describing you as an enemy massing forces at your borders? All around your borders, under various reasons, all legitimate of course.

Unfortunately, that is not my skepticism that modified my view, but NATO participation in rough aggression, against legality and international laws. And if you read my very first participation (well, one of) on Ukraine subject was to ask why NATO followers were so upset about Russia's actions as the model followed was NATO's one.
Double standards I would say: EU/USA impose sanctions, Russia blackmails, Putin's regime, Obama's administration, etc.
