Even if Russia succeeds in fracturing NATO and is successful in their attempts to occupy Ukraine the Ukrainian people will continue to resist them and the Russians will find any occupation an absolute nightmare thanks to Ukrainian drones.
And even if the Russians withdraw tomorrow and give back all the land that they have conquered the Ukrainian people will continue to kill Russian warcriminals from afair with drones that they either smuggle in mail to Russia.
Either way Russia will never be safe and Russian soldiers will never be safe to step outside to even mow their lawn.
