Actually there is only one way to know for sure whether serious pain is indeed being unleashed on the PA and its jihadi proxies in response to Uri.
GOI will say nothing. IA will say nothing. A few tantalizing tidbits will be leaked on SM, but no official confirmation will be forthcoming.
OTOH, ISPR and GOPak will say nothing if a serious jhaapad has been delivered... for H&D reasons. The usual tamasha of b*tching and moaning that we've seen on Paki media since (at least) Modi's reference to POK and Baluchistan on Aug 15th, will continue at an even higher pitch of shrillness. However, given that the baseline was very shrill anyway, it will be hard to determine any significant difference that could be attributable to a successful covert IA strike.
You know what WILL happen if the strike actually took place and TSPA felt pain? Paki proxies in INDIA will be activated at full volume. Rajdeeps, Barkhas, Sagarikas, Karan Thapars, Indian Express, The Hindu, NDTV, CNN-IBN. THIS is where you will suddenly start seeing the tune change. From the Uri attack until now, Congressis were trying to frame sly jabs at "chhappan ki chhaati Modi" who "failed to respond forcefully to Pakistani terrorism". If a big raid took place and hard jhaapad was felt by the Pakis, the same Paki mouthpieces in Indian media will do a 180-degree turn... "uninterrupted and uninterruptible talks are the only way", "the spectre of nuclear war", "it is the poor people of Cashmere who will suffer in a war", "we are not the US, we are a poor country, don't be irresponsible and risk international isolation that could hinder economic development"... all these kinds of statements will suddenly start coming out from Pakistan's Track-II rundies in a desperate attempt to reconfigure public opinion against whatever action Modi took (without telling anybody).
Mark my words... this is where you will learn the truth!
