Nobody is going to give you anything unless you specifically advocate and stipulate how and what you are going to be doing. Even with the submarines - do you realize the cost, the economy of scale needed to build the suitable shipyards, the skill and expertise and the export projections needed to make production of these incredible submarines feasible? How about F16/F15 and F22s - you are also going to supply the spare parts, training, and new aircrafts?
I don't know if example of North Korea is suitable, but there may be some parallels as what Israel may face in terms of arms embargo. North Korea, which typically relies on its own manufacturing, buys some stuff from China and doesn't manufacture everything, and it is purely militarized economy. And most of their equipment is junk due to reliance on its own manufacturing base and on old Chinese surplus.
It's wonderful that you brought up submarines as an argument against what I said. Not only can I make them much quicker and less expensively than any other country, I can repair them and ships without having to cut open the hull like they do, so both the shipyard and the drydock where submarines are held would benefit.
Skill and expertise, I only need available once, and then I can replace a swarm (or up to 4) engineers with 1 robot, and there can be many robots.
Also, I have lots of confidence in Israeli ingenuity, and if other countries want to get in on this (unless some other country besides Israel decides to give me a contract bigger than a few hundred thousand first, sorry) then they will trade expertise for technology.
