How would you even know that? Are you an expert on the Russian missile inventory? For example, Russia is still using tanks from the 1960's and 1970's (as well as their more modern tanks).
If you have actual proof that "the bomb parts are clearly from an ukrainian missle [sic]" and that Russia does not have those particular missiles in its inventory, then post it here.
Why do you never post any actual evidence of your unsubstantiated︀ claims? Who is the real shill here?
