I think suffering is relative: has there been a time in recent history of Russia that wasn’t associated with some degree of struggle for the average inhabitant? And there also wasn’t ever a timeframe long enough where any form of healthy opposition could be institutionalized to endure over longer durations.
Also I’d say that by Western standards even the pre-war living conditions of many Russians would qualify as poor. So their scale is vastly different to ours.
How would the EU scale such operations specifically? My understanding is that the hardware used here is comparatively minimal and Ukraine uses (and produces) multiple times the amount of drones used here weekly. And i don’t think those were super high tech drones either. So that surely isn’t the limiting factor here.
This really comes down to planning and boots on the ground to execute the plan. I am relatively sure that the west is sharing satellite images and other intelligence regarding targets with Ukraine. But you can’t really expect the EU to help with manpower in Russia.
