The reason for sending cluster munitions to Ukraine is that the West
cannot manufacture shells anywhere near as fast as Ukraine fires them.
The only way
to keep Ukraine fighting
is to take them from the large stockpile of cluster munitions.
I understand the logic of this, but it doesn't eliminate the danger
that the unexploded submunitions will pose after the fighting stops.
I wonder if anyone has calculated what fraction of unexploded
munitions left in the battlefields will come from cluster munitions
fired by Ukraine. If it is a small fraction, in the end Ukraine's
use of cluster munitions will not make a big difference. If it is
a large fraction, then it will be the main cause of that future danger.
