That idea seems to be less relevant since there are Baltic states and Norway already bordering Russia. Edit: If Russia really needs buffer - it is big country,

That idea seems to be less relevant since there are Baltic states and Norway already bordering Russia. Edit: If Russia really needs buffer - it is big country, they can create it inside Russia`s border. But they do not need this buffer because Russia`s army compared to NATO is nothing - buffer would not help. But Russia has more nuclear missiles then NATO. And that is more powerful then some mythical buffer zone.
