The U.S. currently has around 2400 fighters and attack aircraft. They will be replaced by 1946 F-22s/F-35s. Thats around a 450 reduction in jets but the next generation of fighters will be far more advanced and capable than current fighters so it wont really matter very much.
Do you have any source to these numbers?
Well, if we look at the Russian armed forces, they too are cutting big time in Navy, army and airforce. I mean in quantity not quality..
The efficiency of weapons do increace all the time, right?
It's not just Russia, i think most of the Western Armed forces is cutting the numbers.
That's definitive the case with the Norwegian defence these days, less troops/fighter etc etc..
