Pervez Hoodbhoy in Economic and Political Weekly:
Although the army has been extremely reluctant to admit that radicalisation exists within its ranks, sometimes this fact simply cannot be swept under the rug. Last week, the army was forced to investigate Brigadier Ali Khan for his ties to militants of the Hizb ut-Tahrir, a radical organisation that seeks to establish a global caliphate and thinks its mission should begin from nuclear Pakistan. The highest ranking officer so far arrested, Ali Khan, comes from a family with three generations of military service and is said to have a strong professional record. It is said that General Ashfaq Kayani was reluctant to take this step in spite of incontrovertible proof that Khan had militant connections because he feared the backlash. Four army majors are also currently being investigated, but this could be just the tip of an iceberg.
