Re "Cameron's Gamble" [June 3]: Regarding the critical issue of Britain's future in Europe, Prime Minister David Cameron looks to be clueless and sitting on the fence. It was not until pressure from within and outside the Tory party had peaked that Cameron reluctantly performed one of his infamous U-turns and promised a national referendum for the next Parliament in four to five years' time. The British public might vote to stay in the E.U. if Britain's membership terms were renegotiated. Predictably, Cameron never spelled out which terms he intends to renegotiate and how.
