The Indian strategy here should be to ensure Pakistan isn't involved with any of this. Pakistan will want make itself feel important by adding pressure upon Qatar to make concessions to the coalition led by KSA. This is something India must stalemate at every stage.
There are hundreds of thousands of Indian citizens in not just Qatar, but each of the other belligerents (KSA, Bahrain, UAE, etc). We must do nothing to piss them off.
I don't think Pakistan will be able to do much here, they've tried offering their "good offices" to mediate, but have been rebuffed by KSA and UAE. Plus, this is largely driven by US in the background and they'll not let
Napakis get their claws deep into this- see how RawHeel's wings were clipped?
Pakistan trying to put pressure on Qatar would be the same as
geedar trying to intimidate a lion. US with it's base in Qatar doesn't need anyone else moving into their sphere of influence, much less the
Napakis.
What Pakistanis can do is offer their escort services- troops,
bums etc at the feet of their masters and try and get some major concessions in return- a cap on Indian workers, support on Kashmir etc. But after their failure to walk the talk during the Yemen crisis, it remains to be seen how far the KSA princes will trust Pakistan.
This is not to say that
Napakis do not have any leverage.Terrorism (along with absolute lack of dignity and honour) remains their biggest leverage and if the KSA offers enough- support against India, free oil, free money etc. they'll crawl into GUBO position in a blink of an aye.
In fact, China and to an extent Russia are best placed to exploit this situation along with Turkey. Should the push come to a shove, Russia and China can easily move in to "protect" Qatar and gain a few airbases and huge gas deposits in the process.
This could see the formation of a US-KSA-UAE axis on one side pit against Russia-China-Iran-Qatar block on the other.
Napakis as usual will look for corner to plonk themselves in and wait for the call to be sodomised by whoever emerges as the bigger dog.
