I've kept an eye on Stratfor fairly closely since 9/11, and I'd estimate their batting average to be about on par with Garth Brooks' (in his stint in the minors).
Seriously though, they made a very bold prediction that relations between Israel and the U.S. would suffer incredibly, possibly to the point of breaking off relations entirely. Wishful thinking on their part, I suppose. Monumental stupidity over there. Their reports read like poly sci grad students with a chip on their shoulder.
