The question is "Do we ( the West ) want Ukraine to exist as a free and independent country". If we do, we cannot proscribe what they do with the weapons we supply them with. Unless the Russian civilian population get a small taste of what Ukrainians have had many years of, they will continue to bury their heads in the sand and accept the SMO as something happening beyond their cares.
Why do you think the only openly anti-war party in Russia was banned from last week's General Election ?
