Bigger ie numbers of people or GDP.Do you really mean to say that the size of the nation determines how capable the plane is and its sales?
Canada geographically much bigger than France and Canadian economy is quite good and yet they have no plane to produce or offer.
on the other hand, SAAB has produced and sold more Gripen then France has sold Rafales ..
The logic is very clear there are only two ways that the French try to get the orders, either by intimidation or by bribing. Egypt and Qatar orders seem to be political orders set to ensure that the UNSC member France will veto any move against these countries. Also the advantage is a good plane.
But then when you look at all orders that were lost.. Korea, Switzerland, Brazil to name a few..
Sweden does not intimidate others they simply have a better way of "management"
The political weight of a country is in direct link with its GP. So yes, USA or GB+D+SP+IT weight more than France alone. And a weapon sale, specially a fighter one, is also a political affair (see Qatar purchasing 3 differents fighter so as to purchased a large political umbrella).
Sale in Egypt : no need to have another UN member in the pocket : they already had USA. But Egypt didn't want to rely only on USA. They wanted another plane so as to bench mark the F16, and the US support. They are so delighted that they want 12 or 24 planes more.
Korea : Rafale won technically. But loose politically.
Switzerland : Rafale won technically. But loose politically. In fact no winner in this competition. Rafale remain in the course.
Brazil : Embraer wanted to share the dev. of a fighter. Rafale and SH18 were mature. Gripen NG was again on the drawing board...
