Dictation on what? The major issue between Pakistan and America in post 9/11 and all the issues that came about, relates to Afghansitan. When this issue is resolved, there wont be much to argue from both sides.
In all this, India will be the major loser, not just from investment point of view but more importantly from its national security as well. With no American shoulder to fire its guns from towards Pakistan, the future is bleak for India in Afghansitan. American-Indian nexus to use Afghan soil to spread terrorism in Pakistan, with India acting as front office while America staying behind the closed doors, that game is no longer viable. With India refusal to send it troop to support American ally in Afghansitan didn't go well with the Americans. Western world also now know the stupidity of propping India against China as Doklam standoff proved India meek and week surrender is not worth pinning hopes on India to act as bulwark against China. With India failing to achieve the objectives on both against Pakistan and China, its utility has diminished.
India left to fend for itself in Afghansitan is a very real scenario, something Pakistan has been patiently waiting for. What impact American withdrawl will have to India own national security with Pakistan western flanks become secure again, its something I am sure the south block in New Delhi understand.
