The Tosfos Yom Tov informed Klal Yisroel that the tragedies of Tach V’Tat occured due to talking in shul. Other Gedolim explained the causes of the holocaust. The Gemora (which is also long after the period of neviim) explained the causes for the Churban.
It is abundantly clear that our Gedolim today and in the past are highly capable of telling us explicit causes or aveiros that triggered specific contemporary tragedies in Klal Yisroel and in the world.
