You have to keep in mind that the decline in profits is mainly from selling fossil gas, that is the gas not liquid, to the EU. Blowing up oil infrastructure is a new thing.
For the last 6 months the US hasn't been able to give weapons, but there's nothing stopping us from lending satellite and human intelligence to the targeting effort, and giving strategic recommendations based on centuries of experience of being continuously at war. It would be weird if that all didn't produce a positive impact on how effectively Ukraine can fight the strategic war.
In terms of fighting courage and tactical knowledge they've been doing it all on their own, yes, and I'm sure they're better than the US at this point which is saying quite a bit. But I think on things like where to bomb the refineries, the US already has lots of footnoted maps and diagrams drawn up that saved some time and increased the impact.
(And the happy synergy of "Hey you know what would help this war effort? If you did a bunch of long term damage to Russia's economy in ways they can't sanction-dodge their way around" "Hey that's a really good point" is a fun thing from the US's perspective, I'm sure.)
Russia’s gas exports to Europe, once its primary export market, have slumped because of the political fallout from the conflict in Ukraine, while Gazprom, which has a monopoly on piping gas abroad, has been the most tangible victim of western sanctions.
Ha Putin, you bet the sanctions work! Remember this is how bad it was in 2023, this year will probably be way worse after Ukraine has also begun to take out depots and refineries. Rumors are that Russia is beginning to lack oil to service both their population and the war!
The oil industry is by far the biggest earner for Russia, so Gazprom posting such a bad result can only mean the Russian economy is feeling some real hurt from the sanctions.
I know. I sat there for a moment thinking what's that Cyrillic g in front of the G?! Why wouldn't that be their logo... whatever, I hear they're going under anyway.
