Ukraine calls for setting up a system whereby the assets of a country that launches a war of conquest will be seized and used to fix the damage.

It is fair to take Russia's assets, and those of Putin's cronies, and put them into rebuilding Ukraine. Let's do it. But we should not suppose that other dictators who in the future start wars of conquest will be vulnerable to the same tactic. Once they have seen this response to Putin, they will take care not to store their assets in countries that might not be on their side in a war.
