This line of believing chief is being repeated so many times without addressing the issue.
We trust him, he claimed that one day after the fight which means he would have done his due diligence and ascertained the facts before claiming the kill. On day 1 it was called 'an aircraft' next day only it was formally announced it was f16. But issue is when we have evidence why are letting these conspiracy theories develop? Indians will belive but other military powers won't see it with suspicion after every claim we put not much to substantiate it? For Indians if you even lost everything you will be supported, maybe people become little angry but the end of day it's our force, our people bonded closely, the claims are not made for us but for whole world and mostly for Pakistani public.
If such doubts keep arising will any Jihadi fear retribution? They will infact feel encouraged that their force fought for them and won over bigger enemy, is this how we plan to create a deterrence? We put the proofs and they deny it that's a different story, our evidence is credible enough so publicly they may not accept but deep inside every Pakistani will know what happened and PAF cheated again. Surgical strikes were accepted by majority in Pakistan and were disoriented with fear even when they denied it. They may say something in public but they knew this happened.
This all look more problematic because doubts on air strikes are already there without complete information, now this only compound the problem. This excuse of somehow giving up or exposing our capacity to enemy also doesn't really make much sense. Show them to all other countries officials, get formal statements if this is really so secret.
Not everything is about believing or not believing chief, they are only making it more suspicious and doubtful by not coming forward. Wait till poltical mudslinging start and see the reputation tank even in own country, let it become big and try salvaging later. What a mess.
