If you mean Russian oil exports, I thought the bulk of those went to Europe and China. It looks like 8 or 9% of US oil imports have been coming from Russia. About half our imports are from Canada. I’m not sure what percentage of US oil usage would be Russian import, but it doesn’t seem like “war chest” level?

Edit: on further inspection, it does seem like a large dollar amount. And if you look at 2019 numbers, we imported a much larger fraction from Russia than in 2021. I still think much more Russian oil goes to Europe

They’ve been seizing all of that money. It’s mostly unavailable at this point.
