I love Kallas but nah.
Russia is an empire and behaves like an empire, the Russian federation needs to be split up into all its member states.
Of course this automatically gives back all territories to Ukraine including Crimea, but it also ensures for instance Georgian independence along with many states oppressed and manipulated through Russian propaganda.
Let's see how much Russia is willing to spend on military, when they have to pay for it themselves...
PS:
Russia actually has a lot of cool legislation and principles in their society that give rights and protect citizens, but it's all ruined by Putin, corruption and the FSB. Not unlike how Trump is ruining USA ATM.
If both could get rid of the corruption and have real democracy, they could both be very good societies, equaling the best in the world like Scandinavia, Japan, Switzerland etc.
Imagine how wonderful that would be! Instead the people are allowing them to be racing towards a dystopia. 😒
