Russian and Chinese Surface to Air Missile (SAM) systems are really good. Modern versions can detect and target most stealth aircraft at a range of 15-35 miles, depending on radar cross section and electronic countermeasures in use.

Not correct because of physics. Ground based radar is still blocked by terrain and the horizon, meaning that low altitude attacks are still quite effective against only ground defense. That is why Ukraine's air force still exists and is still causing issues for Russia. It is also why shaheed drones are causing problems for Ukraine.

The bigger problem for low altitude attack is AWACS + fighters and interceptors with look down/shoot down capability. The MIG-31 has been a major problem for Ukraine because it has long range radar + long range missiles that can hit low targets. NATO and other US allies have integrated air defense where data from AWACS and other aircraft can be used to target low altitude targets.

As far as stealth goes, the notion that stealth aircraft can be targeted at medium ranges has not been tested on the battlefield.

Their radars seem good. Russian “hypersonic” missiles [1] and S-400 batteries [2] are being taken out by decades-old Patriots and ATACMS. They’re demonstrably garbage.

The Russian and Chinese air defense systems might detect but not target at a long enough range to matter. Those are two different tasks and fundamentally how stealth works in practice. Knowing an aircraft is out there does no good if you can't resolve a firing solution. Detecting at a range of 15-30 miles is a small comfort when an F-35 can carry anti-SAM missiles with a range of 100 miles.

There is also quite a bit of empirical evidence in recent months that the Russian systems do not work that well generally, since they seem to be incapable of defending themselves against non-stealth Cold War era US tech.
