Dr. Yousaf Butt has an insightful post on Reuters, which points out that “France’s torpedoing of the agreement [to relax sanctions in return for concessions by Iran] appears less related to genuine nuclear proliferation concerns than with trying to curry favor with anti-Iranian countries — like Saudi Arabia and the United Arab Emirates – who commission and buy expensive French military, satellite and nuclear hardware.” The post goes on to note:
… France penned a military contract with the United Arab Emirates in late July. The billion dollar contract for two spy satellites … Similarly, just a month after the deal with the UAE, France also signed a billion euro contract with Saudi Arabia — a bitter rival of Iran — to overhaul four frigates and two refueling ships. … The French ambassador to Saudi Arabia explicitly expressed his hope that the Kingdom would seek French help in implementing its “huge program…in the nuclear field.” Such long-term infrastructure contracts could be worth roughly 40 billion euros to the French.
I highly recommend reading the whole post.
