Nigel, this is an astonishing misunderstanding of British history. For 500 years, from Henry VIII and Elizabeth I through Marlborough, Pitt, Palmerston and Churchill, Britain's grand strategy was to prevent any single power dominating Europe. We did so through alliances, diplomacy, intervention and, when necessary, war. We fought Spain, Louis XIV, Napoleon and Hitler not to withdraw from Europe, but to shape its balance of power. The EU was the modern, peaceful expression of that strategy. Instead of balancing France and Germany from outside, Britain sat alongside them, exercising power from within. We were one of Europe's three great political powers. Brexit voluntarily surrendered that influence while leaving us exposed to European decisions. You appear to think British foreign policy was about keeping foreigners out. It was actually about keeping Britain powerful. That's the difference between understanding 500 years of statecraft and mistaking the English Channel for a foreign policy.
