Yeah, they think Russia is still run by Stalin or something. ANd they completely and apparently blind themselves to the reality of what has been going on in Ukraine since at least 2014.
People have to want to know the truth to know it, and be willing to drop false beliefs if they are found to be wrong.
They just revert back to Russia annexing the Crimea. Again, not something that Ukraine had as part of its territory, but then again Ukraine has been under the control of another country for centuries. That control has been passed around several times, usually be defeat from war with neighbors.
