As James Montier has pointed out, Europe is certainly cheap but only if you assume low probability of a bad Euro scenario. Basically his point is that there is more fundamental risk in Europe and stocks are pricing in a low probability of a major crisis (Euro breakup, etc). They are not cheap if you assume a Euro breakup or long period of Japanese style stagnation.
