On the one hand, Carlson being against it makes me assume that it's probably a good thing, but on the other I'm usually pretty against the use of landmines because they have a strong tendency to sit around for a long time and maim random civilians.
But if he said the sky was blue I'd have to go check for myself.
The landmines that Biden approved are battery powered. While they are still indiscriminate killing machines, they will self-neutralize rather than remain dangerous for decades to come.
I mean they're being invaded, and by Russia out of all countries. Just like their use of cluster ammunition, they probably decided it's worth the risk.
