We are seeing improved _US_ ISR in last 20 years enables UKR to hit RU assets. What UKR is fully capable of doing is follow up predominantly US supplied intel, especially for longer range / standoff strikes.

EU part of NATO has improved ISR (helios, sarlupe, copernicus etc) but nothing rivalling US tactical and strategic capabilities, i.e. as far as I know, there's no EU system that provides all weather real time targetting.
