Because they made it first, but your point still stands
And who invented the turbo jet engine and sold it for the war effort and whi invented the tank
Who got overtaken in aircraft development and surpassed in tank development?
Development you would be surprised
The US had superior aircraft, so did the ussr.
That depends what you think superior is
Better avionics, agility, speed, and armament.
Dream on
Bro the US had better aircraft. Give me 1 British aircraft that was better than US aircraft at the time
Beside, as is the case with China, Sweden and now Italy with Hungary being official subtree (and once hungarian aviation is added), if players dont flock to these trees when they offer multiple vehicles from many nations (Italy having both US F-16 and UK Tornado ADVand later hungarian Mig-29s and Gripens), then no incentive would help them nor is needed.
I mean hell, with how future of italian ground is shaping, it will be germany that will have worst leopards 2 in game and having smallest top tier leopard 2 selection again, once the hungarian 2A8 gets added and if italians push for the procurement of their own 2A8s.
Same will happen with China after adding US helicopters and M1A2T, and Sweden after getting norweigian 2A8s.
If anything, in the future the big three will need incentives to be played.
