Russia IS at war, and doing fucking terrible.

You're talking an economy the size of Italy (a minor player in the EU) but with a territory more than 59 times that of Italy. It's known for its deep corruption and the invasion of the Ukraine showed the miserable state of the Russian army.

Let's ignore nukes and NATO for a second. Russia attacks Europe and it will get it's ass handed backwards and inside out. If NATO is added, you can add the US army which brings that to utter obligation. Russia would not stand a fucking chance beyond guerilla warfare in its own territory.

All that would be really bad for Europe, probably too for the US, but Russia wouldn't stand a chance.

The problem is nukes. Russia attacks NATO, the US WILL be involved and nukes will be a near inevitability. Once the first Juke goed off, they'll all go off.

Given the current state of the Russian army and the level of corruption at every level, I'm guessing that the weapons that should never be used (nukes) are extremely expensive to maintain, and easy to scrape some money off for your second luxury boat, there nukes will likely no longer be in working order.

Russia fires a nuke, it'll be its own death warrant whilst the rest of the world MIGHT survive.

In any case, Russia is going no where. They might have mighty plans but at this point it can count itself happy if they can be the lapdog of China. I'm much more worried about China, really.
