It is well documented, by Human Rights Watch and others, that **the Ukrainian military **has used cluster munitions. There is nothing to support a claim that Russia has done so. The Pentagon has rejected the earlier claimed evidence of Russian cluster munition attacks:

Commenting on videos depicting alleged Russian cluster munition use, DOD officials stated during a March 1, 2022 press conference that “we’ve seen the same video that you have but we have not assessed that it is definitive with respect to the use of cluster munitions. So we are not in a position to confirm the use of cluster munitions at this time.” In a similar manner, a DOD official stated during March 3, 2022, press conference that DOD was still unable to confirm Russia’s use of cluster munitions.

2. So you've an issue with the effects of a weapon leaving the AOR but no issue with a weapon that still kills people over 70 years later.

Get some consistency man, you're all over the place.
