Ah yes, the sham referendums of the “Donetsk People’s Republic” (Captured), the “Luhansk People’s Republic” (Also captured), the Kherson Oblast, and the Zaporizhzhia Oblast (Both partially under Russian administrative control). The referendums were done with extremely bad methodology, with proven reports of Russian coercion on citizens, limited voting power for certain groups inside of these regions, a lack of identification or any reasonable restrictions for eligible voters, intentionally created pro-Russian parades in occupied regions, and so much more. Only 1 other country has considered the referendums to be valid: North Korea. The UN had little to no oversight of the referendums, its validity was publicly denounced by a near unanimous majority, and the referendums literally violated international law. There’s no actual proof Ukrainians want to transfer to Russia in a large enough quantity to even consider accepting. In short, they did NOT want to leave, some might have, but not nearly enough, and even then, Ukraine will refuse to allow that during a wartime like this, because these kinds of things require Russia to actually be at the table for negotiations, which it has failed to do miserably.
