The destruction of Israel is only one item on the Saudi shopping list. They also desire looser visa restrictions for their citizens -- a return to the sort of laxity that made September 11 possible. And they want smart bomb technology, which would elevate their military capabilities dramatically.
The Saudis remain one of the world's three foremost sponsors of Islamic terrorism, along with Pakistan and Iran. They demand Israel as ransom for their energy resources. And because of America's failure to secure domestic oil production and/or create alternative energy resources, America must kowtow to radicals in robes.
