The EU will fragment and there is no stopping it at this point.
The EUs immigration policies have guaranteed that the EU will break apart.
Either the individual European nations will break away from the EU to regain their sovereignty or those nations will collapse because their immigrants have cause chaos within their borders and fall way.
By the EUs own actions they have sealed their fate. Great Britain is the first to leave but not the last. The rats know the ship is sinking and they wont wait for it to go under.
All part of the plan. Consider how long they’ve been talking about the so-called “two-speed Europe”, with more powerful nations forming a hard “core” (empire) and the peripheral nations treated as vassals. The EU elites are expecting this fragmentation in order to implement their phase two.
