LONDON -- After months of careful planning, it has been the turn of London to suffer the carnage already familiar to the people of Madrid, Jakarta, Casablanca, Riyadh, Istanbul, New York (although not on the same scale) and many other world cities.

The war, it seems, is universal and it has been declared by the new generation of terrorists on every center of civilized society. Next time, according to one sinister Internet message, it will be Rome -- and then, who knows?

Londoners, of course, have had plenty of experience of being bombed. Pulverized by Adolf Hitler's bombers and rockets in World War II, the British capital, after a few years' respite, then found itself the target of persistent and bloody attacks by the Irish Republican Army.
