I agree with you.
Furthermore, the F-35 is by far the most expensive option and Lockheed Martin offers close to nothing as compensations to the Belgian industry.
Admittedly the F-35 is the only one that offers stealth properties but this advantage will soon be outraged with the progress of technology.
Both the Rafale and the Typhoon manufacturers offer large compensations. Belgium would be stupid not to select one of them.
The F-35 will offer commonality with the Netherlands and the Scandinavian countries, but the Typhoon has been selected by the UK, Germany and several other European countries and the Rafale by France.
The choice seems evident!
