The recent confrontations between the Pakistani army and Imran Khan's Insaf Party have revealed new political rules of engagement. Khan's activists and followers dared for the first time in Pakistan's history to attack the army headquarters and tamper with their contents.

The real force that represents national unity, and popularly agreed upon was and still is the military institution, writes Fawaz Gerges. Gerges: Khan's rise would not have been possible without the support and backing of the military and security forces in Pakistan, which Khan quickly sought to abandon.
