First of all, funding our enemies military projects will relieve them of most of the burden for funding the project themselves, which they can allocate for other research. Secondly, Saudi cooperation is indirectly supporting our enemy, unless you think that those weapons you and your new ally will be producing won't be used against Pakistan in event of a war??
Not really, most of what we have you are not interested in, mostly due to the fact that since Pakistan has a small defense budget therefore we have less to offer in certain fields, unlike indian which is spending billions of R&D while at the same time purchasing 70% of its weapons from Western countries as well as Russia, they have access to the best tech unlike Pakistan.
You have a point, however this is only a speculation, we don't know the reality behind this "defense pact", so far the only thing keeping Pakistan and india from going at each others throats was the Strategic Balance, which india has upset by building up its Army, Navy, Air force, and strategic forces as well, add to that American and now Saudi joint cooperation.
Well, honestly tell me, what does Saudi have to offer to india when it comes to defense research and development that india doesn't already have?
An industrial base? But india already has that.
Scientists and engineers who are experts in the field of defense R&D? But india already has them in large numbers, on top of that israeli assistance, Russian assistance, French assistance, German assistance, they have the input from the best of the best the world has to offer, do you honestly think Saudis can provide indians input far better than those of Israelis, Russians, French, American, British, and Germans??
The only thing Saudis can offer is $$$ and oil, i'm not trying to be rude or racist or arrogant, yes Saudis have made a lot of strides in recent years, but india has been in this field for way to long, even NASA has a lot of indian scientists and experts, not to mention india can launch its own Sat into orbit. They even have their own jet program even though they have suffered a lot of setbacks but they have made improvements.
As much as i despise the indians, they sure are a shrewd and determined adversary.
