The EU will stay intact only so long as monies are being transferred from the wealthy countries (Germany and the UK) to the poorer countries and as long as France is allowed to pay subsidies to its farmers. As soon as the richer countries figure this out and pull the plug, the EU will be gone.
EUrocrats will use the poorer countries to supress the resistence of the richer. They will do it in the name of war against fascism and racism. Divide and rule.
