So far, the war is more like a precission strike using missile and then send in the cavalry. But if the Russians start using dumb bombs, the destruction will be massive. I suspect the reason why the ruskies haven't used it because they want to give time to refugees to leave the cities. After some time, all who are left will be considered as enemy combatants. Another thing, China really need to consider evacuating its citizens ASAP. I doubt this war will end anytime soon. Ukraine after all have close to half million troops, backed by western supplies.
