It doesn't though. Raising costs by forcing a country to dodge sanctions is very effective. A supply will never entirely dry up, but it will shrink and become more expensive, and that's enough.
Though of course, sanctioning less developed countries like Cuba, Venezuela, DPRK, and Afganistan does successfully greatly harm their working-class population, and it has.
Sanctions on Russia have crippled their ability to get modern chips for their war machine, so they have to rely on Soviet tech. They hurt Putin personally so much that he went and bought an entire Presidential campaign.
Well that part is true enough at least. Capitalist Russia naturally can't innovate as much as Socialist/Soviet Russia could. Even its highly sophisticated public transport like in Moscow are stuff that the USSR built; they'd probably be filled with high-speed rail by now, like China is, if it wasn't overthrown.
Jesus the copium. What's actually happening is that Russia is able to rely on decades old technology because it was built to work and built to last, so 40 years later they can use it in modern warfare and it's still effective. This also means Russia can allocate its resources to outproducing the entirety of the West when it comes to artillery shells, which is actually what's winning this war.
The idea that sanctions hurt Putin personally so he had to buy an election is also ridiculous. He's now a wartime president, just like GWBush was, so getting reelected is even easier now than it was when he was merely the president who reversed the 8 years of declining life expectancy after neoliberal economic reforms destroyed Russia.
Using academic terms like the Global South doesn’t instantly make you smart or right.
Especially when you consider both geographically and historically Russia has been part of the Global North. Often guilty of the exact same exploitation (or as in Ukraine much worse) as it’s peer set…
Lmfao the USSR directly funded and supported emancipatory movements all over the world, like Vietnam, Cuba, Korea, Bangladesh, Palestinian resistance organizations like the PFLP, etc; even directly supplied wars against "israel" for that last one. Afganistan is about the only one where the US and USSR funding opposite sides turned it into a warzone instead.
Russia's interests are still broadly aligned with most of the world against Imperial core countries. While they're not socialist anymore and have thus stopped funding Vietnam, PFLP etc because it's not profitable for the capitalists that are now in power since the USSR's overthrow, they continue to support the sovereignty of Global South countries like Syria, Venezuela, etc, and are a core part of BRICS. There's a reason sentiment like this is common in third world countries.
And if "Global South" sounds too academic for you... I'm not sure what to say.
It's just speeding up dedollarisation at this point. Trade is increasingly done in other currencies because the US dollar is just a minefield of sanctions and regulations. The US had this power back when they produced everything people needed, but nowadays everything's coming from China, so why involve a third party in your trade that can freeze your accounts for no reason?
