He may not have agreed with the way the present EU. is run but he would have had the trust in Britain being able to change it from within - he would not have run away from it. What I find hard to swallow is that, on the one hand the Brexiters are trying to picture Britain as being totally without influence within the EU. like a 6 year old child having sand kicked in its face. But on the other hand they are telling us how dynamic we are. If Britain feels that it was not able to influence the EU. how does it feel it can influence any other trade block ? In fact from all laws passed by the EU. the British supported 88% of them - this is a higher success rate than any other country - the British have helped to make the EU. what it is today, with all its faults.
One of the biggest faults with the EU is the disastrous Euro project. It has placed countless millions into poverty. There were only a few misguided politicians such as Clegg who supported the idea. Churchill, like Thatcher, would have given up long ago. Cameron tried to get a small adjustment to free movement and failed miserably. The responsibility for Brexit lies solely with Merkel and others who gave him no concessions whatsoever.
