Well, This might sound like a bad news for India, but i dont think it really is. Since India still cant even meet all its local defence needs indigenously, so how does afghanistan expect India to meet their defence needs? India of course will prioritize meeting its own army defence needs before it can think of exporting any such equipments to a foreign country. Another solution for India will be to give soft loans/gifts/credit to afghanistan for them to buy/procure much needed weapons from say Russia(i think i red somewhere that India sign an agreement with Afghanistan and Russia whereby India will provide funds to Afghanistan so they can procure/buy weapons from Russia), that will be a good way of helping the Afghan army, since India is not really in a position(well not yet) to meet afghanistan defence needs.
Afghanistan already has alot of U.S weapons and to some extent Russian as well in its inventory so i dont understand why they are so desperate for other weapon supplies. They should focus more on their economy and signing a peace treaty with the other rebels/guerilla fighters/Taliban so they can focus on development. This will be better than always focusing on weapons/military(though its needed as well). For i dont think there will be any peace without negotiation with these scums called Taliban, they have to be relaistic and deal with it, since the Taliban are going nowhere and are there to stay, but we and the Americans are foreign countries, hence we cant stay there forever. So hopefully the Afghan government will act responsibly and look at a larger picture. Good luck to Afghanistan and the Afghan people, for they have gone through some pretty tough times these past decades.
