The only way to make Putin stop the war in Ukraine is to squeeze any Russian benefiting from links to Moscow. Western authorities must continue to 'seize and freeze' the assets of Russian oligarchs and family members of Putin's inner circle, wherever they try to hide them.
Putin's government may be responsible for horrendous crimes against humanity in their invasion of Ukraine; however, it's hypocritical to impose sanctions on Russia but not on the US for invading Iraq for equally unjustified reasons, or on Israel for invading and annexing Arab lands.
These sanctions are unfair and risk leading to widespread Russophobia. It's not only Russian oligarchs being targetted; there are also many informal sanctions being imposed on Russian culture and businesses. This is cancel culture stigmatizing an entire population for the crimes of one autocrat.
