The people who should weigh the risks to Ukrainian civilians are Ukrainians themselves.
mmm, no, i don’t think you can say this absolutely. if Pakistan is invaded by India tomorrow and they say they’re going to nuke Delhi in response i’m still going to be against that even though i’m not directly affected and they’d be in the right to do that, legally, politically, and militarily speaking. wars are not fought in a vacuum. additionally, what can be justified on the aforementioned three grounds does not inherently map to what is morally justified, and in this case i think there are obvious alternatives which can be taken that are much less morally dubious.
That’s not really the same thing.
If Ukrainians use cluster munitions, they are putting Ukrainian civilians at risk not Russian civilians. They are free to accept that risk for themselves. Particularly because Russian troops also pose significant risks to Ukrainian civilians.
I would oppose Ukrainian use of cluster munitions in Russia, for the same reason I would oppose use of Pakistani nuclear weapons in India.
If Ukrainians use cluster munitions, they are putting Ukrainian civilians at risk not Russian civilians. They are free to accept that risk for themselves.
if you change the hypothetical to “Delhi rebels tomorrow against BJP rule and Narendra Modi says he’s going to nuke Delhi in response” i don’t think the arithmetic changes just because now the people are from the same country and that country is “free to accept that risk for itself” of what such an action will do. the usage is bad full stop; the consequences are avoidable through not using them; there are less morally dubious alternatives available which will have the same net outcome. these are valid arguments with or without borders being considered.
And if you change it to “Delhi rebels threaten to detonate nuke in Delhi, Modi responds by dropping cluster munitions on rebels” then it’s not so clear any more.
Ukrainian civilians are at risk no matter what happens. The ones who are ultimately responsible for deciding the fate of Ukrainians are Ukrainians themselves.
You may think you see a better option, but they don’t have to agree with you.
