Must be Andy doing the whole "3 day war" routine again? None of the Russian government/MOD officials ever said anything about a 3-day war.
On the flipside - members of Ukrainian government/MOD did say a bunch of thing.
Arestovich (member of Ukraine's intelligence community), March 2022 - the hot phase of the war will end within 2-3 weeks. Budanov...Where do I begin. This guy made several predictions both in 2022 and 2023. Then he must have got tired of being wrong, so his latest prediction was "this war will last for a very long time".
