You cannot do two things.
On one hand you say that you want to isolate Pakistan and yet you put red carpet for the person who has just now snubbed you by visiting Pakistan.
Because of such kind of schizophrenic message, likes of SAARC are unlikely to agree.
Saarc nations may not agree on India’s efforts to isolate Pakistan
The reason is simple: "Isolating Pakistan" is itself a crazy goal and when you yourself are not serious about it, why will others take it seriously?
From the looks of it, this entire thing is looking like following :
1. BJP does not want to 'waste' time on this any further. They have more important goal: to look like as if they are generating more jobs and catering to regional issues. Its election time after all. Modi and government are no longer in power. Things are run according to party's election agenda. Further, they have "given full authority" to Indian forces. Meaning nothing. Military in india cannot do a damn outside india unless political will is there to back it. So, you will see some encounters but nothing else concrete. Simply put, the rulers don't have time to invest there. I guess they either have data or they believe that military or security matters do not matter to the public and dole outs determine the election results.
2. Opposition parties have also understood this. So they have taken a rather interesting stance. They "fully support" government. Bascially it means, if any action is taken, they will claim it as their as well or atleast "India's victory" and NOT "BJP's action". That said, incase of a miss-fire they will simply put whole blame on BJP. Further, in case of no action, it will be used as a tool to bring Modi's popularity down.
So net-net: Most probably nothing will be done, some kind of propaganda will be made or some token action will be done. Economic actions are joke anyways. They were taken because you have to give some kind of reaction. So easiest and lamest actions were taken. The only issue is, do people in India will react to non-action as BJP is thinking they will : ie "We don't care". It may be a massive mis-calculation or may be it is the truth. I honestly don't know.
