When someone is whatabouting the WWII atomic attacks in order to pretend that the Holodomor is normal and fine, then yes, it's exactly the defense I think it is. There's an order of magnitude (or two, depending on which sources you take seriously) of difference in casualties. Further, one was an act of war on military targets, and the other doesn't even have that "justification," whether you consider it a justification or not.
