What a load of malarkey. The US intelligence apparatus discovers that a Japanese company has backdoored all its hard drives which are apparently also installed on USN vessels. The US, out of benevolence for this non-US company's reputation, I guess, decides to agree to a secret deal with its ally. The secret deal is that US Navy personnel will be put onto Japanese naval vessels, which in no way remedies the problem of backdoored hard drives that supposedly exist. Random JMSDF captains know the details of this supposedly secret deal and discuss it freely without consequence. Imagine believing this. Japan has been a friendly country and valuable Pacific strategic ally for decades. What exactly is the US supposedly gaining here? Maybe it's more likely there's an exchange program between allied Navies, like there is with dozens of other countries??
