Sounds a tad delusional to me, given how fashionable Israel-bashing has become in certain circles, mostly the circles Theroux moves in.
I find the world monstrous. Just in the news, that Israel won't let eight Palestinian Fulbrights — and the way the United States has cravenly rolled over and let Israel dictate whether these eight scholars, high-minded people, can't even get out of that horrible place in Gaza to come to the United States to be Fulbrights — that's the kind of thing I'm attacking. That's the kind of pain I'm inflicting. That's the kind of no-punch-pulling, unsparing, pitiless, even cruel attitude that I try to launch in the book.
