One of the things Israel has going for it is an incredibly adept arms industry that specializes in military high tech. The US has taken advantage of that more than once in the past.
One place where Israel shines is in unmanned drones and its export models were the undisputed star of the recent Paris arms exhibition.
The Russian military has been drooling over Israel's drones for quite some time now, and has been negotiating to buy them, interesting in itself since Russia never buys foreign arms systems. The deal appears to have finally gone through, but with an interesting trade off involved: the Russians have agreed to put a freeze on their prospective sale of S-300 Pantsyr anti-missile defense systems to Iran.
This is one more sign that the Israelis realize that they're going to have to deal with Iran's nukes themselves...and soon.
What the Russians have in mind is to re-engineer the Israeli technology to create their own drones. However, there are a number of safeguards the Israelis can implement to neutralize the impact of this, and I'm sure they'll take reasonable precautions.
