Russia has no business in anyone else's country. Period.
If the Russians feel threatened, then they can build a stronger wall -- on Russian territory.
Invading your neighbor, so you feel safer against an assumed bully means you are a bully yourself.
Your logic is not very smart, Rasika. Your logic is myopic. Russia may be your favorite football team, and you may love it as much as you want. But your football team cannot take over another football team.
Don't blame Europe and America just because they have their own warts. They were smart to defend themselves against this Russian aggressor. Russia is the party that is completely in the wrong.
If Russia is afraid of NATO, it should consider joining NATO. Then they will be safe from the threat from the West. But... they must then live and abide to the reasonable demand that Russia does not invade another nation.
Don't defend the bully. That is very Stockholm syndrome of you.
