Actually, Pakistan would not be happy not only with the presence of India and Turkish forces, but it would be unhappy with any solution that can effectively stabilize Afghanistan. Becoz a stable, strong Afghanistan would prove to be a big headache to Pakistan(they have border issues, and Afghanistan claims almost half of Pakistan). Hence, Pakistan would always try and keep Afghanistan as destabilized as possible. Therefore, so anyone wanting to resolve Afghanistan's situation must not pay attention to noises coming out of Pak.
There is a difference between being unhappy and getting one's panties on fire. You know what? However unhappy Pakistan get's with the prospect of Indian presence on the other side of the Durand line....
It still has the biggest incentive for Afghanistan for a durable stability. India has no imperialistic ambitions, never had one, shouldn't be a problem for most sensible Afghan nationals. However, InA boots alone can ensure stability and security of a nascent nation state in the long run, having undergone decades of turmoil and bloodbath of its citizens, an aka "Great Game".
One country after another has played blood spilling games in this country for attaining their short term gains. There has to be FULL STOP. This country belongs to its natural inhabitants, Pashtuns, Hazaras, Uzbeks, Tajiks...whatever...and they should have FULL rights to lead a life of peace and prosperity, see their sons and daughters getting educated and married, reap the harvest of having a country to call their own without the fcking necesssity to serve as somebody else's
Strategic Depth.
And if an Indian Army presence can extend a helping hand...so be it.
We have the most extended experience in COIN operations then any other country in the vicinity operating in similar combat terrain. We are more similar to these men than a Canadian or an American. Lastly we have more to lose if Astan goes down the road to hell.
