If Russian sanctions have backfired, why has Russia stopped gas sales to Europe? Why doesn't Russia just continue the status quo?
"Russia cuts off gas exports to Europe via Nord Stream indefinitely"
Western Europe is going to freeze this winter, the Russian Ruble is more valuable now after the sanctions, Russia is making more money on fossil fuels now because the prices have skyrocketed and Russia is still occupying Ukrainian territory, so YES the sanctions have backfired
