IAF lost its last plane on May 28, 1999. It conducted a few hundred combat sorties between then and July 4, 1999 bombarding dozens of Pak positions with devastating effect. Hardly chickening out is it?
But IA and Indian MoD conducted investigations and punished the culprits who were negligent.
Does PA have a history of ever accepting mistakes and punishing guilty? Why is PA afraid of an open investigation of why it started Kargil, what assumptions it made and why it failed in its obejctives?
