Thanks for the recommendation, will take a look at it. What I've read of Chomsky so far is often a critique of (mostly, but not exclusively) US Imperialism, so I'm curious what this person is arguing

I will read it. Regardless, though, he is associated with the left and him going down for this would be bad PR for the left broadly, which sucks - that's my only point other than we don't know he's done anything untoward here.
