alt Hacker NewsUkraine dramatically reduced Russian fuel export revenue, and the sanctions did so even more.
It was really coming to the point of urgent existential threat to the Putin regime this spring, before Trump and Netanyahu bailed him out, first by doubling the global oil price and then by relaxing sanctions.
And Ukraine's drone / cruise missile portfolio includes things like the Flamingo, more than twice the payload and range of a Tomahawk.
If Ukraine had access to Tomahawks, Russian oil industry would not exist at this point. With drones after two and halve years of attacks with multiple hits at the same refineries Ukraine reduced Russian fuel production at best by 20%.
Flamingo is still mostly vaporware. For precise strikes against Russian factories Ukraine uses either Storm Shadow or domestic Neptun.
But that just shows again that drones are not particularly effective against most industrial targets and even against oil installations the damage is not lasting.
Or consider how US was able to destroy the bridge in Iran yet Crimea bridge and bridges in Rostov that are absolutely vital to Russian war logistics still stands.
