Three wrong premises here. 1. That EU needs Russia to fight US militarily, economically. Can never happen. All along, EU has used US to fight Russia on all fronts. Germany has had suspicions against US but that is nothing to worry about. What has changed? 2. Based on premise 1 of US-EU relations, Russia cannot join. 3. EU is held together by NATO in which the US is a major player. NATO is historically, politically and militarily built on anti-Russian sentiment. Look at Syria for example. That has not changed and is not likely to change soon.
