It didn't say the missiles were Russian-made and the serial numbers were traced to Ukraine, it didn't say the missiles were Israeli-made and the serial numbers traced, it just says "the serial numbers say Ukranian missles" and gave no details as to how that was determined. There's a shit-ton of propaganda bouncing around. There's plenty of much more convincing evidence that the Ukranians are faking atrocities or pinning them on Russia. There are people getting killed by both Ukranian and Russian troops; this is inevitable in war, and it sucks. This particular propaganda, however, is weak sauce. The more crap you mix in the less you'll be able to convince people to side with you. I'd like to see more convincing evidence, and I'd like to see it in text rather than an emotional video.
