I like what you say and I too am totally in favour of it.
However, the problems are:
1. Fighters from Tajik base would not be able to threat PAF as India doesn't have the support system in those areas. In today's fight a fighter without force multipliers like AWACS or ground based radar network is way too vulnerable. Especially since PAF will definitely send out its AWACS with its fighters to face India.
2. We can't send in our own boys as that would be death sentence for them if Panjshir falls. Also, the hills of Panjshir is completely different than the terrain we have mastered.
But, I would like if India retaliates against PAF and lights up LOC in warning, which Modi wont do because like it or not, such a move will cost us too much diplomatic coins.
As for high table of Kabul. It is a loss, but not a big one. Unless India accepts the inevitable and takes away PoK and GB, India would always remain a minor player in the region.
I am sure RA&W knew that ANA was going to fall and had prepared Massoud's NA with support. Yet, it seems it wasn't enough as Porkis brought in high tech war in the game. It obviously was out of syllabus for RA&W, as they didn't think that Porkis would dare to show its hand so openly.
And, yes, India did lose some in this game. But, it didn't have any option either. Given Russia is reluctant to play and rather willing to screw over the former allies of US to undermine US authority in global scale, India obviously was not getting much support in Tajikistan. Also, recent souring of relationship with Iran under Chinese influence also blocked another route for India.
So, it is best for India now to dust of its hand and prepare for the next event.
1. Support any resistance financially and with equipment.
2. Prepare to take PoK and GB in the first opportunity.
Like it or not, except for FATF connection where Pak can shift terror camps to Afghanistan to get out of grey list, Pakistan had gained little and lost more. They have always gotten bitten by the snakes they fed. Nothing says that it will any different now.
As for FATF, the FATF don't care for geography so much as the money trail. Even with camps shifted to Afghanistan, the money trail would link to Pak and if India plays well, Pak will remain in grey. Especially after showing its hand in Afghanistan.
