THE BURNED OVER DISTRICT

That the Taliban is now setting up shop in Karachi, Pakistan. Needless to say, like any new gang in town, they are muscling there way in and seem to be doing vary well, too.

But there is a new gang in town. Hundreds of miles from their homeland in the mountainous northwest, Pakistani Taliban fighters have started to flex their muscles more forcefully in parts of this vast city, and they are openly taking ground.

Taliban gunmen have mounted guerrilla assaults on police stations, killing scores of officers. They have stepped up extortion rackets that target rich businessmen and traders, and shot dead public health workers engaged in polio vaccination efforts. In some neighborhoods, Taliban clerics have started to mediate disputes through a parallel judicial system.

The grab for influence and power in Karachi shows that the Taliban have been able to extend their reach across Pakistan, even here in the country’s most populous city, with about 20 million inhabitants. No longer can they be written off as endemic only to the country’s frontier regions.

In joining Karachi’s street wars, the Taliban are upending a long-established network of competing criminal, ethnic and political armed groups in this combustible city. The difference is that the Taliban’s agenda is more expansive — it seeks to overthrow the Pakistani state — and their operations are run by remote control from the tribal belt along the Afghan border.

Already, the militants have reshaped the city’s political balance by squeezing one of the most prominent political machines, the Pashtun-dominated Awami National Party, off its home turf. They have scared Awami operatives out of town and destroyed offices, gravely undercutting the party’s chances in national elections scheduled for May.

Good thing the Pakis have nukes to deter these thugs, amirite?
