Europe beating the drums of war is completely of their own doing.
If they had helped America in Iran, then their oil wouldn't be cut off now.
If they had kept their nuclear power plants open, then they wouldn't have an energy crisis.
If they didn't import a bunch of "refugees" who share none of their core values, they wouldn't have a foreign army already hiding amidst their own citizens.
If they didn't attack American corporations for frivolous social media posts, they would have more positive (to them) media coverage.
The list goes on, but at the core of it they, due to overwhelming hubris, shot themselves in the foot.
