The U.S. is offering Saudi Arabia a nuclear deal while bombing Iran over its nuclear program — bad news for Middle East stability and a win mainly for U.S. companies.

• The U.S. is fighting Iran's nuclear program but giving Saudi Arabia the green light on nuclear tech with fewer conditions.
• Westinghouse and other American companies stand to make big money on the Saudi deal.
• Israel is livid, because it wants to stay the strongest power in the region and keep rivals weak.
• The double standard pushes more countries to want nuclear weapons as protection against U.S. pressure.

Outlook: The deal sets the stage for more tension and a wider arms race in the Middle East.
