So you want to increase funding to the UKR armed forces? They seem to be doing well so far.
Item 1. Forbes journalists will not understand cepstral processing, nor even raw fourier transforms, and if you do not understand this, you understand nothing of modern weaponry.
1) The writer claims the S-400 SAM missile system is claimed by the Russians to be the finest in the world. The writer is not even up to speed on non technical realities. The S-500 has been fielded given operators were announced to be in training in 2021.
2) Ranges do matter. The S-500 is designed for 100s of miles of range. Most radars won’t see that far because it’s below the horizon. Airborne radar will see it and announce it, but there is no evidence counter battery ordinance can be deployed in any even remotely effective way since the S-500 and its 4 radar vehicles are just that. Vehicles. They will move. This is true of both sides, btw. Counter battery artillery is of nearly no use against a maneuvering weapon with the launch platform on the move.
3) The S-500 has anti satellite capability. Claimed. Not demonstrated. The Russians actually have a slight satellite recon advantage via sheer geometry and need not imagine an urgent need for anti satellite missions. Their multi spectral imaging vehicles have direct line of sight transmission to the ground stations in Russia that will process the info. US satellites must relay to NRO in Washington for analysis.
