Yes I'm sure you're right. They deliberately send their children on, some as young as 5, to be abused and almost starve as they knew, presumably via their crystal balls, that Lord Dubs would, someday, announce that there would be a scheme whereby they could access Britain. The parents were also sure that they would be reunited with their children (who obviously wouldn't bear any ill feeling toward them) as were such a soft touch. Yes....that definitely seems plausible.
