Hong Kong still has a lot of people that are haters of communism. I was there right after Tiananmen and 3 times since. Killed me every time seeing how things were changing for the worse.
Some holdovers there that still believe or assets that we have maintained assisted them in escaping.
I understand... but in a police state, airports are the most carefully controlled points, especially international travel - especially travel to the US {for a high security official} - especially with a relative.
Perhaps the resistance gave him & his daughter false papers... with a high security official this all seems dubious. His advancement in office was partly due to incompetence in his department; I would expect a CCP counterintel officer to be at the airport - someone in his own department. Would they recognize Dong? If so, would they call it in and temporarily block his boarding a plane?
These issues deplete Dong's credibility, at least until he proves his bona fides. It is a rocky relationship; Dong might provide some good material but supply some misinformation where the CCP considers it important. He would be under the control of expert DIA interrogators. It would be helpful to have a second source (for confirmation) but at his security level that is not very likely.
It sounds like Dong could provide the intelligence to lead to Biden's impeachment and subsequent prosecution. That would be some real bona fides!
