Earlier this week, a suicide blast ruptured the relative calm that had returned to Pakistan in recent years. The attack at a mosque in the northwestern city of Peshawar killed more than 100 people and stunned many Pakistanis who thought the days of such horrific suicide bombings were long behind them.
While Monday’s attack was among the worst in the country in a decade, the blast doesn’t necessarily signal a return of terrorism so much as an escalation of a problem that never really went away.
