Yes seriously. The US and EU are the reason why Russia sees the need to defends its western borders. This conflict is as much about internal politics in Ukraine as it is about geopolitical failures.
If the EU members would cling less to the US (instead of letting them build a rocket shield in Poland), Russia would possibly have fewer reasons to keep a pro-Russian buffer zone.
