Sure after all, we can agree to disagree.
Firstly, India can insist US but the real picture is, except the will and would be, India is not included as such as having no influence or to share in this matter hence, excluded realistically. It is realized that India cannot play any major role but on other hand as you mentioned about Russia in Afghanistan, again, India is wrong in this perception that US will never allow as such hence, all the tussle in region. I don't know how explain further but I hope you may read beyond nationalism in this regard w.r.t. geopolitics. These are hopes what you defined as compare to the real picture. US let India to have an access but events unfolded then after actually alerted D.C that India used Afghanistan only to harm Pakistan and trust me, Intel do hold much information than any media baseless reporting. Furthering the situation, Pakistan stopped helping anyone outside but was kept busy for the cleaning inside due to interference of the rival and we succeeded though on other hand, US did realize the damage in Afghanistan that needed Pakistan for the same to contain the situation to which India failed. Lines are drawn and writing is on the wall that India did use an opportunity being short sighted against Pakistan but done more loss to NATO/US and Afghanistan that in my opinion, such times were good for us in the end that today situation is in our favour and US-Pakistan are back online but per same level and frequency.
Pakistan did draw the picture based upon reality and what should be done necessarily for stability of Afghanistan and if India has anything to offer, would have been on board since long ago but No. China has a lot to say in this regard that you will understand in last lines of this post otherwise, US is totally in disagreement whatever you tried to describe here. Speaking of border sharing, how much border does India share with Afghanistan? and in broader aspect, the answer will speak of India's irrelevance in this picture. No country wants Afghanistan to go in hand of terrorists hence, China, Pakistan and US are in talks for the peace of Afghanistan.
Speaking of recent drone attacks, you may not be in knowledge that, same were done at border while hunting most wanted criminals as Khurasani and Mansoor so you can understand that such are results of what COAS said clearly and furthermore, are testimony that US & Pakistan are now working together to get rid of maniac that Kabul regime has been hosting since long. This is how international relations works like working for oneself nation interest and helping each other. No drone strike inside Pakistan but I repeat it was border area and Pakistan is doing whatever it can only based upon actionable Intel provided.
Not a surprise from your side to read the same as such but looking at the statements and things turning into favour, the outside world is saying something different. Yes, Pakistan is always committed to get rid of terrorism and work with the world or US in this regard though, India can see it the way it wants to but does not prove it as compare to reality. India has already signed LEMOA with US and on other hand Russia knows the outcome of such pact which is totally against Russia's interest in the region especially in Afghanistan that US wouldn't like it at all. Actually, based upon the pact signed by NaMO with US and all the interest with Western World, it is India trying hard to be the part of powerful group while on other hand, the new power pack in shape of China, Pakistan & Russia, is already formed and is reality. India having no other choice as not being on track with China & Pakistan, couldn't contain the situation hence, needed US more than any other party in the region while on other hand US rebuilding relations with Pakistan are actually telling the story that how situation is changed now. India, in my opinion, did or will understand that what really happened here and become a front-man for US to contain China & Pakistan due to its own rivalry where I wouldn't blame US openly that taken full advantage of the same for nation interest same as what India did for. So, the Russia will be doing so whatever suit its interest and there we all see a strong group that will work for betterment of region that only regional powers can do such and it is obvious.
