Why not? For almost 2 decades no US astronaut got into space without the help of a russian spaceship.
The Sukhoi SU-57 is arguably the most sophisticated warplane today - at a much lower price than the self-defeating F35.

By now fully import substituted (no Western parts) and in serial production.
And this one is a direct competitor to the Boeing B-737 MAX and Airbus A-321 NEO:

It has a wider cabin than the A320, a wing which allows a higher cruise speed
and a higher capacity in its base variant, the MC-21-300.
It is allowed to fly to the global majority.

Have you noticed that US airlines lately complained for "unfair" competition because
US passenger jets couldn't fly over Russia when heading for China?
Sanctions cut both ways, and Russia is by land mass the largest country on earth.
Russia is fully self-sufficient, has >95% of the resources it needs
and get's the rest from China. Passenger planes need robust chips,
not 5nm AI-chips. The Russians can build them reliably in masses.
But have you noticed news about rare earths lately?
Looks like it isn't Russia who is without resources.
Nvidia had a 95% market share for AI chips in China.
Sanctions reduced that to 0%. Huawei is doubling their yield
every year since the first sanctions. Sanctions work - but not
for the benefit of the sanctioning party.
