That's a bit harsh on the most successful 4.5 gen in the world. Which doesn't even come with American goodwill...
Lol! "The most successful" 4.5 gen in the world? How many air to air kills have the Rafales scored in actual combat? Last I checked, it was still zero. The last time the Rafale fought in a proper air to air combat, it was a one-sided defeat. The best combat record for the Rafale is by the French Air Force bombarding third-world militaries in Libya and Syria.
There are other 4.5 gen aircrafts who can claim better achievements. Most notably are the J-10CEs, and the Su-35s. The J-10CEs defeated the Rafale itself, not some outdated Mig-29s or Mig-21s. The English-speaking world can doubt all they like, but that doesn't change the facts.
Yes, the Rafale is still an excellent 4.5 gen, one must never underestimate it. And the way the Indian Airforce had incompetently used it doesn't do it justice. But the most successful 4.5 gen in the world? That's really over the top.
