I dont know much about any of the Gedolim who people anticipate some sort of statement from, but I feel I am correct when I say that they do not:
Listen to the radio
Read newspapers
Log on to YWN or any other website for news
Join in the “hock” in shul after davening
to be fully aware of what is going on. Someone must make them aware of what is going on. If they are not aware of what is going on, or the extent that something is going on, unless you ascribe some ruach hakodesh to them, how should they be aware of what is happening in the “street” and to comment on it as they see appropriate?
Anyone with more insight into how a kol koreh is formulated, please correct me if I am wrong.
