Truth is, there were people who, from there description, were Tzaddikim too, post war such as the Baba Sali, the Gerrer Rebbe ( who sensed things with ruach hakodesh) (I think it was the Gerrer Rebbes, if not than another, not the point)
I wish I heard of more Tzaddikim today, but in light of The Rebbe telling us that the responsibility to bring Malach has passed on to the individual men, women and children from the Tzadik etc, shortly before the Rebbes stroke, it makes sense…
