Nihil est incertius vulgo, nihil obscurius voluntate hominum, nihil fallacius ratione tota comitiorum. (Nothing is more unpredictable than the mob, nothing more obscure than public opinion, nothing more deceptive than the whole political system.)
Unless you count the political backdrop, which in any case is a familiar one to many international readers, I don't think there's anything that I would call essentially Brazilian in João Gilberto Noll work. In that regard, it translates very well to a cosmopolitan audience.
There's been real hostility toward political poetry in the U.S., hostility or, at best, incomprehension. I'm speaking of those who have institutional power over what gets published, over grants andprizes and reviewing. Most of them, though not all, arewhite and male. But even as American society is unravelling, becoming more violent and punitive, wonderful political poetshave been emerging.
