India and Pakistan can take their fingers off their nuclear triggers: In a sign that relations between the two countries are thawing, Pakistan said yesterday that it has arrested all the leaders of Lashkar e Taiba, the group believed to be responsible for November’s terrorist attacks in Mumbai. "The entire top, middle and lower-level leadership has been arrested," Pakistan Interior Minister Rehman Malik said—124 arrests in total. This is good news for Pakistan-India relations, which have shown signs of thawing. On Wednesday, India scaled back its demand that all suspects be extradited to its soil. Lashkar, though damaged, has not been eliminated. It still maintains a presence, particularly in Kashmir.
