Today’s attacks on Lahore show that the battlefront in Pakistan’s struggle against Taliban militants has shifted south.
The militants are taking the fight to Punjab, Pakistan’s most populous province. This region, which borders India, is the political and economic heart of the country. It is also from where the officer corps of Pakistan’s army is largely drawn. Lahore, its capital, is regarded as Pakistan’s most cosmopolitan, tolerant and historic city.
