The European Union's leaders said they wanted the United Kingdom to remain in the EU. But Brussels offered only minimal concessions to British Prime Minister David Cameron, undercutting his effort to sell the benefits of continued EU membership.

Now the Eurocrats who dominate EU policy are attempting to push the U.K. out the door. London should refuse to play their game: slowing down the process would maximize its leverage.

The principal argument for the EU is that is has created a common economic market. The most powerful argument against it is that continental elites are attempting to create a superstate by stealth. The EU's post-vote behavior reinforces this criticism.
