The mines Russia is going to leave behind are probably going to kill more civilians than cluster mentions.
I think it took decades to demine Cambodia.
I leave it to the Ukrainian government to decide what to do. They are in an existential fight for their existence; they are under no legal obligation to avoid using these weapons since they aren't treaty signatories; the Ukranians will only be using it on their own territory not somebody else's sovereign land; and I suspect most Ukrainian citizens are willing to accept the risk if it helps drive the Russian Invaders Invaders back.
Agreed. Still, the "moral high ground" thing counts for something. Lowering ourselves to the level of the fucking Russians and their mercenaries makes us equal to the fucking Russians and their mercenaries. No better, no worse. Worse, according to people like Tink.
The Ukrainians are free to defend their country. They are not free to demand we give them nukes, cluster bombs, biological weapons, etc.
