What interests me is the American balance of power embodied in the film, that is, multiple organizations investigating the same incident. That US military officer is mainly an executive unit, that is, searching for evidence based on intelligence to the so-called "hiding points" of weapons of mass destruction. But after returning with no success many times, he became suspicious of the information on which he was based, and then became involved in the vortex of truth finding.
In an executive department, doubts about the actions performed are a management problem that any organization will face. In the US military, there seems to be a very special mechanism, that is, its executors can conduct questioning operations through multiple channels. One is directly through the military, the Pentagon; the other is through other intelligence organizations, such as the one in this film. CIA.
If I believe that the film is based on the premise of certain facts, I can think that the film reflects that in American organizations, multiple channels of information are often added in order to achieve checks and balances of power. People in different organizational units can communicate information to other organizations through these channels, thereby realizing information non-closeness and avoiding "information dictatorship" in a certain organization. And "information dictatorship" is sometimes the cornerstone of "power dictatorship."
Although it is a battlefield, even in the most disciplined army, the idea of balance of power is still the most fundamental.
