"Saeed has emerged as one of the most vehement opponents of reopening NATO ground supply lines through Pakistan for forces in Afghanistan. The polarizing invective Saeed and his cohorts, both hyper-nationalist and jihadist, are peddling makes it more difficult for those in Pakistan seeking to repair relations with the US. As for how great an irritant he has the potential to become, Pakistan is unlikely to take significant and lasting action against him in the near term and so much of that depends on how LeT evolves and how the US responds. But it’s already clear that in the last few days he’s become a much greater irritant than anyone would have expected."
