We shouldnt do anything under threat of war...
I think you mean - We never do anything without the threat of war. We U-turned in 2001 after being threatened to be bombed into Stone Age. We banned LT and Jaish-e-Mohammad after the 2002 war drama. We started acting in FATA after US stepped up the bombing runs and even sent troops across. We took out jihadis at Lal Masjid after they launched war on Islamabad. We all but made LOC as some sacred line after US threatened us during Kargil.
Yes, we will issue some brave statements and enact some dramas for public consumption but trust me - a climbdown is coming. There will be no war.
