I agree with your thoughts there, @BertieBotts.
The older children adopted from Russia were never the blank canvases the adoptive parents imagined them to be, and they resisted the projecting of American expectations of 'rescued' Russian children.
Russia was absolutely right to stop the adoptions, especially to the US.
On top of all you describe, there was also a thick layer of 'saving the children from the Red Peril', with children taken from humble but secure and predictable surroundings and plunged into a world of OTT materialism, bedrooms decorated with Disney images and paraphernalia, etc, and often called by americanised versions of their names - people adopting children who basically swallowed the capitalist vs Communist gospel without ever chewing it and had no idea of the emotional, psychological, and spiritual needs of the children, who saw tired old orphanage playgrounds and spare, shabby buildings, and thought only in terms of Russia Bad/ America Good, and bringing the narrative to its logical conclusion - "I am doing a heroic and patriotic thing."
Of course in reality, while the chdren were happy to have a family adopt them, they were not thinking "I am saved from this wretched post Soviet existence in the Evil.Empire and I can now enjoy the American Dream". The idea that the children could miss the staff and their friends from the shabby orphanage, the plain food, the squeaky beds with the chipped paint - and wouldn't gleefully embrace out and out materialism, wall to wall Disney decor,, etc was something many of the parents couldn't accept at all.
For some adopters, the idea that not every single person in every corner of the world cherished the American Dream close to their bosom was a reality they simply couldn't wrap their heads around.
The level of American patriotic pride and the psychological impact of the Cold War and decades of anti Soviet propaganda in the US weren't appreciated by the people vetting adopters.
