Its impossible for the EU to act as a unified block because it fell to the US trap by accepting Easter Europe countries to be enter the EUBecause Europe refuses to get its act together. Instead of creating a fairly united block of responsible and sovereign nations we have a collection of US vassal states that go along with US neocon/neolib aggression against the world, which in turn undermines global peace and stability.
