First of all, Mr. Simcha613, you should show a little more respect to our Gedolei hador. Has it occurred to you that maybe just maybe the Gedolim thought of your Genius question and decided to do what they did anyway….??? Unfortunately, like many in our impoverished generation you clearly don’t get the concept of Daas Torah.
Second of all the answer to your question is so simple. The gedolim have called for many days of tefilah over the past year and half for the terrible situation of the war and the hostages. Although it is terrible that the war is still ongoing and not all hostages returned, that doesn’t mean that there cannot be another tzara at the same time which we need to daven for!!!
Please, a little common sense…!
