Well, yes. American films obviously have been soft on China because they've been desperate for access to the Chinese market. You don't bite the hand that feeds. In a similar way, if a significant amount of film production moves to the UK, it's likely that criticisms of the UK would be more muted. In the long run, this creates a national security threat when our media is inundated with non-neutral messages about other countries that are not acting in our best interest.

The easy way to see this is to reverse your lens. We've been the beneficiary of soft power from Hollywood for a century. It'd be ridiculous to lose that power without at least trying to preserve it.
