Can NATO bog down Russia through Ukraine in this war till Russian economy is drained out as the war prolongs ?
I know this is not asked for me, but let me answer that anyway.
The short answer is yes.
There are only enough money for you to hold and use for war, after that money is gone, you cannot pay for war material, you cannot pay for wages, you cannot pay for food and etc (well, you get my point)
What NATO and the West is doing is isolating the money factor for Russia. Russia is trying to sanction proof their economy but nothing is actually sanction proof. Money is probably the number 1 factor for all wars. So if you hit people with their money, it's usually is where it hurts.
What the sanction do is freeze Russian Asset in US, EU and the West (including Japan some other Asian country.) Also US is putting a hit on Russian Central bank, by frozen their ability to use USD, and taking them out of SWIFT. Which mean 2 things.
1.) You cannot raise money by putting out debt to fund the war. Each debt have to be guaranteed and supported by your economy, effctively, what the US is doing is to taken out Russian ability to raise debt in USD or Euro or GBP. Which mean the Russian can either raise debt on Rouble (their currency) or Chinese Yuan. The first one is kaput, it's worth as much as toilet paper right now, which mean this is not going to be good for raising money. Yuan is the only possibility, however, that would depend on Chinese willingness to finance a war with Ukraine. I honestly don't see how, as Ukraine is China strategic partner and this war does not hurt US or EU or NATO a bit, which mean there are nothing to gain for the Chinese.
2.) Russia will have a hard time looking for parts and material in the international market. Russia is resourceful but not resource proof, there are things that Russia does not have and have to depend on outside world. And by taking them out of SWIFT, they cannot use international transfer to pay for their order. Which stop them from making supplies.
Another issue for Sanction is, it basically taken out Putin and his people money. First by taken Russian Oligarch money out of EU and force them to put it back into Russia or China or some other place that were no sanctioning them. Then US hit Russia Central bank and make their asset worthless by making rouble worthless. That will really hurt the pocket of Putin and Friends.
