It's really weird how narratives alone can change the direction of nations,

We used to say we are the arsenal of democracy to justify all the right wing coups we sponsored against socialist leaders, even if they were democratically elected, and now a major US party's establishment has zero qualms helping socialists if the socialists are the ones who are going to the defense of the global democratic society, because "we're the defenders of democracy."

The joking innuendo became a legitimate foreign policy planck!

I think this is part of an overall tone shift in the US' culture, a rise of Radical Sincerity. Everyone is so burnt out of wink and nod cynicism after decades of it being the norm in one iteration or another, that the punkish backlash to the status quo cynicism and fake smiles is to play what was once made fun of as childish delusion completely straight.

Sincere fantasy stories, abandonment of lampshading tropes, exhaustion with wink and nod fourth wall breaks, shift to a sincere insistence on following through on the values we were told to aspire to, through religious upbringing or through the narrative of national history we were taught.
