Right, though I don't think there was any ambiguity in that, rather only how resistant the ants were to the effects. I said earlier the King wouldn't be able to breed anymore, but of course it makes more sense the amount of radiation from that close isn't going to cause only infertility. I'm actually happy with this conclusion for two reasons: The ants aren't so divine, after all, and Netero really did know what he was doing (and didn't die for nothing).
I think the general structure of this arc is kind of interesting: The ants rose phenomenally, shook two countries quite thoroughly, but then were almost arbitrarily swatted dead (if you consider the fact they were defeated by nongovernmental agents in a small, limited operation). My sympathy was never on the ants' side during this arc, but assuming this is indeed how it will end, they do deserve both respect and pity.
