Why wouldn't the international community leverage sanctions as a way to help cripple the Russian state's ability to wage war, whether through financing or sourcing parts for producing new weapon systems?
I mean, yeah, it sucks that the Russian people have to pay the price for their leaders mistakes, but a lot of these Russians also appear to support the "special military operation" on some level. Either way, the west would be foolish to not use maximum pressure on a country that is waging a war of genocide on another country that did nothing to them.
The war has devastated the Ukrainian civilian population as well. The only way to win the war is to wear down the ability of the Russian state to wage war using economic, diplomatic and military pressure.
