My understanding is that the CIA influenced the rise of modern art over Soviet realism, eg, by hosting shows and bidding up prices.
That is “created” in the sense that a movement would have been smaller or fizzled without their patronage, but not “created” as in invented absent an underlying cohort of sincere artists.
If you believe the CIA was an important and necessary part of the movement, you seem to agree they created.1 modern art, even if they co-opted rather than created.2 the style.
