Irrational EU

Sir: James Forsyth’s otherwise excellent piece on Brexit talks (‘Britain’s winning hand’, 26 November) suffers from the flaw of most British analyses of the EU: the presumption that the EU is a rational actor. If that were so, Greece would not be in the euro, Europe’s borders would not be guarded by Turkey, and David Cameron would have returned from his talks with a deal enabling the EU to keep one of the world’s most successful countries in the union.
