The EU isnt a single mind you know. Bunch of countries with their own interests. Pretty sure atleast half of them wanted to sanction Russias ass, whatever USA thought. 60% of EU does not need USAs help to not like Russia. What makes you so sure its mainly USA that wants to sanction Russia? Somehow I think Eastern-Europes EU countries want those sanctions more than the US and so the US shows its support to them. A lot of countries got scared when ruskies took Crimea. Russia should concentrate on showing Europe that its not a threat, not throw "USA did this" into the argument. Once EU calms the hell down, so will the US eventually.
