Speaking of the Siyum HaShas, there is certainly discussion there about Moshiach’s coming.
There are certainly those who hold that the world will continue more or less as is, except that “Vihaya Hashem LiMelech Al Kal HaAretz BaYom Hahu Yihye Hashem Echad uShmo Echad”, that even the gentiles will be 100% sure that Hashem is the Creator.
But regarding what I perceive to be the main point of your thread, I was hoping to hear some of the numerous kiddush Hashem stories that must have occurred to so many.
From the coverage I saw thus far, it seemed clear that the secular world simply cannot relate to what a simcha this was for so many dedicated people, men, women and children, each for their own unique and important role in this wonderful individual and global simcha in finishing Shas and all the hard work, sacrifice, etc. that this entails.
