Russia - threadbanned users in OP

Ah yes Iran and Libya, sanctioned states doing so well. North Korea another. Now Russia has oil and gas, that and waving around nukes are their only trump cards, but yep they're big ones and Europe's reliance on these commodities as Russia's primary customer particularly Germany has indeed resulted in the farce of paying Russia to keep prosecuting this land grab war. No argument there. This has caused a further spike in oil/gas prices to Russia's benefit. Certainly in the short to medium term. However....

what do you think is moving the ruble to a 15 year high,

You see that's not nearly the positive you think it is and Russia trumpets and spins it is. Even Russia knows this. When it first tumbled in value among other capital controls they raised interest rates to a massive 20% to try and control it, they've since dropped it three times to try and dial back its rise(last time I looked it's back to 10%). That's some clever accounting in response to a major crisis, not the positive you think. It's so high because while they've been raking it on from oil, but those "sanctions that aren't working" have meant they can't buy foreign currency, they can't import goods using their cash to nearly the same degree and they can't send their wealth abroad on top of the capital controls of Russia's finance ministry. They've gone from trading back and forth with the world to trading one commodity abroad and trading with themselves. A strong currency means your exports become more expensive and that's OK if you can use all that cash to buy stuff from outside for your economy. They can't.

TL;DR? The rise of the rouble is actually proving sanctions are working.

And for the future? Russia is cut off from the industrial, financial and political world, at least the part of the industrial, financial and political world that actually counts. A mickey mouse trade deal with say Mali won't come close to making up for the loss of a similar trade deal with say France. Though I can see putin not caring and prefering a new Soviet Union commonwealth of little mickey mouse states where Russia's the boss. They're cut off from international air travel and for the foreseeable. Even their apparent best buds China have closed their airspace to the Russian operated Airbus/Boeing fleet. Their own homegrown fleet was utterly reliant on now sanctioned western tech for engines and avionics. Can they replace that? yep, but this isn't Soviet times with a long established and much bigger more populated command economy so it's going to take a long time and what they produce will have to be signed off by the international aviation authorities. The same authorities who've been badly stung by Russia. Good luck on securing insurance, so they'll have to underwrite that too. Leasing is dead to them for the foreseeable and that goes way beyond the aero industry. That's before we look at the massive flight of non Russian businesses from their country leaving a considerable number of Russians unemployed and a rising poverty rate since this war kicked off, which Russia's own figures show. Oh sure some oligarch can bring McDonaldski back, but while they can make burgers and chips easily enough, they can't make silicon chips nearly so easily anymore. And that's before we consider the brain drain and demographic timebomb that Russia was looking down the barrel of before all this and has been accelerated because of all this.

TL;DR? putin wanted a return to the Soviet Union of sorts? Well in this he looks to be getting his wish.
