In God is Not Great, Hitchens unequivocally laid into buddhism, though obviously it wasn't the focus of that book, or, as you intimate, much of his work. But within, he attributes imperialism through to kamikaze indoctrination to buddhists / buddhist dogma. I suspect the absence of (m)any proximal adherents willing to publicly debate him on the topic is why we don't have the same wealth of quips and ripostes from him around this pseudo-religion as compared, say, christianity.
