Miracles happened and will happen to Israel. For example, on Purim and Chanukkah the Tachanun is omitted and/or Hallel is recited and/or the Torah is publicly read. Today, on Jerusalem Day or recently on Yom HaAtzmaut, many, mainly Zionist Jews deviate from the normal weekday prayer, and add parts they consider to be a proper expression of their joy.
Strictly from a halakhic point of view, what has to happen that warrants a public Torah reading or the omission of the Tachanun?
