We know it well enough, since USSR participated in the Pacific Theatre
Declaring war on Japan in August 1945? The USSR "participated" by showing up for the yearbook photo. Typical Stalinist land grab. And quite frankly, it's hard to celebrate the Soviet contribution to the European front when Russia was originally so happy to indulge and assist Hitler. You let a wild dog off the chain, you deserve to get bitten.
I would be comforted to hear reasoned arguments that the situation currently bears no resemblance to the past.
Clever. So unless I conclusively show that the current era has absolutely no similarities to your vaguely-defined "past," I'm wrong. That's a lot easier for you than having to support your use of the term "fascism"... but then, you've already admitted that you're using it imprecisely, to say the least.
I am too old to learn a new [programming] language. The languages I know will suffice for now.
Understood - and incidentally, I would like fries with that, Grandpa.
