The video imagery in both versions may or may not be on a planetary scale; that's never specified.
No, it's not clear how wide-spread that is, but I don't know if that's important. The Martians who came to Earth are the ones that did that. Maybe the others are fifteen feet tall with four arms and two legs. But they didn't come here.
"Cleansing of the hive" is the term used, yes, but still to me that's not "ethnic cleansing" which is very specifcally targeted. What's interesting now that I think about it that even the Martians themselves had among them those who they felt, perhaps instinctively, needed eliminating.

Sort of makes me think of the green monkey story. Supposedly, if you take a monkey out of a troupe (presumably not an actual green monkey in the first place--yes there is a species called green monkey), paint it green and put it back, the other monkeys will tear it to pieces because it's different.
And that's about the size of it.
