Send weapons to help the Ukrainian defense (already being done). Also apply sanctions, but only targeted to people in power (e.g. freezing assets in Switzerland, not buying more gas from Russia). I'm aware that these can indirectly affect laypeople (e.g. not buying gas creating unemployment in the gas sector) but that's just life. But what I find dumb is sanctions targeted explicitly at laypeople. Those who don't support their government don't deserve them, and those who do get more reasons to close ranks with their government because "the enemy" is now actively making their lives miserable.
