I think they have just hit that point where the denial is unnecessary really. They still do it out of reflex and as part of the admit nothing doctrine all modern Nazis subscribe to as just part of how they grind down opposition. It's not so much about hiding the crimes now, because the entire world order is complicit in these crimes. Stopping Israel would be stopping the entire global capitalist hegemony. They know this on their end, so it's really just that low effort because that's all that is required of them.
