Russia has become the fifth largest economy in the world and the largest in Europe, surpassing Germany and the UK, according to statistics of the World Bank. [PDF]
Let's see how Italy does under the same kind of sanctions...or better yet let's not because that would essentially amount to genocide. It's only thanks to the fact that Russia is one of the most self-sufficient countries on the planet, second to only the DPRK, that they have managed to essentially shake off this attempt at a second genocide via economic warfare (because apparently the first one in the 90s wasn't enough for the neoliberal imperial death cult). Showing yet again that the way that western "economists" measure economies is fundamentally wrong and does not actually reflect their real size and strength.
That's the problem with liberals, they think of themselves as exceptional. The G7/EU heads think they run the 'best' countries. So when they sit around a table and ask, 'Whose economy would survive a week of sanctions?' and they all shake in fear at the thought, they think it will have the same effect on everyone else. In many cases it would.
But they can't help but see Russia as backward—how could it possible withstand their worst nightmare? They're apparently unaware that they created the nightmare. Russia may be capitalist but it's not quite so neoliberal just-in-time. Still, I don't think the west understands what's happened; they're going to get a real shock when they try to turn up the dial on China because they haven't learned their lesson yet.
I was making reference to the lib statement that Russia will struggle because "they have the GPD of Italy" Which they might've, a decade ago or so.
But even if they still did, your response is correct, Russia is much more self reliant, something that western economies don't seem to be capable of being at all, so they try to measure economic success in ways they can pretend they are strong and their enemies are weak.
