My bet is they will focus on unveiling defensive achievements. Indeed it is a time to allay fear and alleviate pressure internally. Solidarity can be built around advancement in defensive technologies such as Bavar-373, which is likely to be a focus of the upcoming parades. Iran is facing opposition that even she has not encountered to this degree before with the Bolton/Pompeo/AIPAC/Zionist/al-Saudi alliance's machinations. Had Iran built Nuclear weapons already, it would have had the upper hand. But alas, in this game of chicken, Iranian patience is running thin... and centrifuges may soon start running at full-speed. The two cars are running towards each other at full speed, and Iran ought to throw out the steering wheel to show that she is steadfast and vehement in her resolve to pursue her defensive capabilities. Nukes have limited practical purpose in today's world, but since our enemies have them in the hundreds and thousands, so should Iran.
