I was thinking something similar recently. When an army leaves the safety of its homeland to invade another country, it becomes vulnerable to its supply lines being cut off and being stranded in a foreign country with lack of fuel, food/water, and/or ammo.

We’re already seeing scattered anecdotal examples of this happening to the Russian invasion force even without their supply lines being directly attacked. I wonder how difficult it would be for Western powers to assemble a fleet of drones, stick a bunch of Ukrainian flag decals on them, and then attack and disrupt the main Russian supply lines into Ukraine.

It would only take a few days of that before the Russian army runs out of material to fight the war with. Then Ukrainian troops can force a surrender, round them up, treat them appropriately under the Geneva Conventions, and then offer and encourage them to accept political asylum in the West. (Same with Belarus if they invade). Destroy or confiscate the materials.

Then boom, Russia no longer has an army. And without the West ever directly attacking the Russian (or Belorussian) homeland.
