Even if it was just pure anti-personnel clusters, we have evidence of that far back in 2022. So even then he would be lying. For example there is photo graphic evidence from the bomb disposal teams in Ukraine of 9N24 submunition. Which is soviet pure anti-personnel submunition for their cluster dispensers. It has no other purpose. It isn’t even dual use dumb HEAT/FRAG submunition. 9N24 is pure fragmentations anti-personnel round with simple contact fuse. Hit’s ground, the explosive core along the main cylinder shaped munition explodes and well the whole outside wall is lined with steel balls to be thrown in 360 all around.
Similarly 9N210 HE/FRAG munitions have been documented. Again useless against armored targets, only use case is against soft targets like humans. As have 9N235 again HE/FRAG sub munitions been documented.
All same purpose, just little different sized and exact design for different dispensers. Some those might theoretically have fuses with self destruct. However the whole point about cluster munitions being bad is fuses fail, including supposed self-destruct fuses. There is no such thing as 100% reliable fuse, even self destruct one.
My source: Armaments Research Services articles on the subject. I’m sure there is bunch of other more official sources also, including listing more individual incidents and attacks. ARES are just convenient source here, since they are interested the weapons technologies and types used in conflicts, so they have bunch of articles of “This specific type of submunitions has now been seen in Ukraine”.
