It is quite clear that Cameron's veto was not down to his growing a pair of balls, or a spine, heart or brain, come to that: it was the inevitable result of overreaching by Sarkozy and Merkel.
Blinded by their doctrinaire EU-federalism, they failed to see that they were pushing the British PM into a place where he simply cannot go. His Party has been split for decades on the Europe issue and even the Opposition Labour Party is divided (though at pains to conceal this so as to increase the Conservatives' fratricidal anguish), much of the electorate that has sufficient education and intelligence to take an interest is in favour of leaving the EU altogether, and thanks to the financialisation of our economy, we need the City because taxing its thieves is what is keeping our gunwales above the waterline.
When the French and German Sir Humphreys are finally allowed to talk some sense into their masters' hot heads, there will be another deal offered. My guess is a temporary derogation for the City from the proposed tighter regulations - perhaps five years, or until some round-figure year such as 2020.
Or, if the French wish to get in another dig, 18th June 2015. The rationalists of the Revolution are more superstitious than the religious they despise, and the bicentenary of Waterloo would afford them a satisfying symbolic revenge. It would be like Hitler's decision to have the French sign the second armistice at Compiègne in 1940, in the same railway carriage where the Germans had to sign their surrender in 1918.
This regulostice would allow time for our pinstriped crooks either to filch what's needed for a comfortable early retirement, or to find positions on the Bourse, the Börse and (of course) the Far Eastern (and maybe Australian) exchanges where all the exciting action of the future will be centred. And the British politicians and their placemen will doubtless reap their Quisling rewards in Brussels and Strasbourg.
At any rate, cancel the flags, bunting and bands.
