well for the Russia sanctions, initially it did have an impact but then both people and corporations found workarounds...

for example, blocking swift does not make money transactions impossible, makes it difficult for the layman in the first a few times.

nowadays, everyone uses crypto/usdt for the transactions and realizing it is actually cheaper and faster than the swift.

for the europe, they still buy the gas even at a higher price. grounding berlin to moscow flights only benefits turkish airlines and qatar airlines as now they profit from being monopolies (connections through istanbul and dubai)

the reality is that people adapt. i am not a trump supporter, i do not agree with the tariffs but that's what trump is trying to do; force people to adapt local goods
