> Furthermore, after the one-time pain, assuming they survive the pain, the sanctioned nation arguably ends up stronger because they're forced to develop in-house versions of things. Which is why North Korea is now a world-leader in... Oh, right. They are an impoverished Chinese vassal, that can barely even keep its own people fed. I don't understand where all this 'Sanctions do nothing' zeitgeist is coming from. Is…
List the countries that are 1. not tiny little jokes of a country and 2. not currently already under heavy sanctions that the US can sanction without harming themselves.
The reason it's a joke of a country is precisely because of sanctions (and equivalents thereof). It didn't becomes stronger due to being cut off from foreign trade - unlike its sibling SEA nations, it failed to develop in large part because of it.
2. Without harming itself? Even one iota? There aren't any. Without harming itself disproportionately less than its harming the sanctioned country? Almost every country in the world. [1] Doubly so if it does so in lockstep with the EU.
Of course sanctions harm the country invoking them. But like going to war against a weaker country, they harm the target a lot more than they harm the issuer. Cuba, Iraq and Iran were all impoverished, compared to their peers, by sanctions. Russia's well on it's way to eating a boot, economically. The US sure seems to be getting a lot of mileage out of this 'one-use' weapon...
[1] China, Japan, Mexico, maaaaaaaaybe Canada, Taiwan, and a few countries in Europe are the only ones I can think of, where sanctions against them would hurt the US almost as much as it would hurt them.
