How the world was destroyed? The season 2 flashback scene of Silo explained

The season's finale shows a flashback from the time before the destruction. It portrays Helen, The Washington Post journalist meeting a congressman during the time of heightened radioactive threats in the United States. This event suggests a bombing event orchestrated by Iran. In the meeting, we see that the journalist wanted to question "if there going to be a strike back" from the US.

This flashback scene possibly hints at the war between the US and Iran that lead to the destruction of the world and compel people to take refuge in Silo like giant structures. This flashback reveals Washington D.C. was recently devastated by Iran's dirty bomb (Radiological Dispersal Devices), hinting at escalating global tensions and environmental collapse.

The journalist asks the congressman if the news about the event is true, this shows that only government officials like him actually knew what happened, which is similar to the rules in Silo. The congressman passes Helen a Duck Pez candy dispenser that in season 1 George Wilkins passes to Juliette. This can be seen as a symbol of rebellion against Silo's rule.

The backstory of Silo explored in detail

Season 2 explains that the earth's surface becomes inhabitable as a result of accumulated catastrophes like pollution, chemical reactions, and climate change. Juliette learns about the existence of other Silo structures and the threats that the citizens are facing there.

They are made to believe that the outside is contaminated to a level that no one can survive. Juliette Nichols uncovers the truth about Silo's larger purpose and manipulation of truth about the outside world that hints that the world is not as toxic and is probably healing from the last catastrophe.

While each Silo is built with various social structures and offers an extent of freedom to its residents. The knowledge of the outside world has been kept a secret for the benefit of the few.

Therefore the flashback establishes that the Silos were designed to take refuge at the time of such radioactive threats. As Juliette digs deeper, she encourages others to question the status quo which results in a rebellion among the Silos residents and disturbs the peace within the giant structure.

The show's Season 3 is currently under production.
