Israel can't manufacture everything themselves. It's just a little country smaller than New Jersey. And they can't get everything they need from the black market, exactly when they need it. This is why the United States has Israel chained to the floor. And Obama knows it, and Netenyahu knows it. I wish this wasn't the case, believe me. I wish Israel could tell Obama to shove it.
Israel depleted a large amount of their guided laser bomb stock piles for their Pillar of defense operation, and needed re-supply. And Obama recently allowed the sale of 5000 guided laser bombs for Israel- to replenish their arsenal.
I'm a practical person, where are they going to get these large quantities of weapons from? I know Israel is a large special weapons manufacturer for many countries around the world. They sell drones, advanced radar systems, and many other advanced special weapons items. But Israel needs huge quantities of re-supply. And at this time they don't have the manufacturing base to provide this.
