They say that the past is another country, but let me tell you that it's much more unsettling to find that the present has become another country, too. In my lost youth I lived in Finsbury Park, a shabby area of North London, roughly between the old Arsenal football ground and the Seven Sisters Road. It was a working-class neighborhood, with a good number of Irish and Cypriot immigrants. Your food choices were the inevitable fish-and-chips, plus the curry joint, plus a strong pitch from the Greek and Turkish kebab sellers. There was never much "bother," as the British say, in Finsbury Park. Greeks and Turks might be fighting in Cyprus, but they never lifted a hand to one another in London. Many of the Irish had republican allegiances, but they didn't take that out on the local Protestants. And, even though both Cyprus and Ireland had all the grievances of partitioned former British colonies, it would have seemed inconceivableunimaginablethat any of their sons would put a bomb on the bus their neighbors used.
