Basically, S. Arabia will pay for equipments from US defence industry. Israel objects and will mobilize congress-men to block the sale. Israel will not block the deal, if US gives Israel money. http://defensetech.org/2010/07/27/i...-tech-to-not-block-saudi-f-15-sale/#more-8405 S.Arabia wants not only new F-15 bit also 72 Blackhawks. Deal approaches 30 Billion $ in value: U.S. Saudi Sale Is Said to Approach $30 Billion Including 84 F-15 Fighters - Bloomberg Conclusion: S. Arabia pays. Israel gets payed. And if Israel does not get payed, it will block US defence industry getting paid. Very sick system you have there EDIT: Sorry wrong forum.
Other nations pay for the products. Israel will make "Monica Lewinsky" in the Congress and also get the products.
