Ukraine went very well for Vlad.
the biggest and richest former Soviet State West of the Don is now locked in a frozen conflict, and won’t be joining the EU, or NATO, anytime soon and he’s got the Crimea, and the Donbas.
Or, without the Muscovite spin:
Moscow has decisively alienated Ky'iv with Ukraine and the majority of its people being firmly turned against reincorporation in any Moscow-led political structure.
Russia is still affected by the sanctions that were imposed at the time and it has suffered considerable loss in various spheres, particularly financial and reputational.
The whole gambit can be assessed as more of a failure than a success, falling far short of Kremlin expectations. However, Moscow can never backtrack on this and admit failure, as it does not fit in its mindset.
So it just tries to keep justifying it and in this effort it is succoured by various stooges.
