It’s easy to accuse someone else of being defensive.

It is no coincidence that Parshas D’varim is always read on the Shabbos before Tish’ah B’Av, as Moshe Rabbeinu recaps the tragedy of the M’raglim (Spies). Chazal say that this incident not only transpired on the Ninth of Av, but it was the root of all future destruction that would take place on this cursed day (Taanis 29a).
