If the US actually cared about Ukraine, we wouldn't send cluster munitions. We have deliberately used these things to make farmland and schools into minefields for decades, we know exactly the harm they cause. Ukraine is fighting this war on their home turf, their home turf is where the cluster munitions will remain undetonated until some child steps on them.

The US wants to see the Russians slaughtered. The PR line is that we want to defend Ukraine, but using cluster munitions is not a thing you do somewhere you're trying to defend. We're perfectly happy to have a bunch of Ukrainians slaughtered if it means we can take down some Russians too.
