If the problem was a PR one, I would agree with you @GiveMeSpanakopita .
But, IMHO, the fundamental problem with H is a national security issue.
Put yourself in the position of the Head of the CIA. You have Omid Scobie claiming that the "royal racists" letter came from KC3's desk. Thus telling the world that KC3's desk is not secure and individuals can swipe materials off the desk.
As the Head of the CIA you are aware of all the intelligence information that crosses KC3's desk that is vital for USA national security. NATO and US forces based on UK soil. NORAD (North American Air Defense, most famous for Santa tracker, but ensuring that Canadian and US airspace is secure.) Five Eyes. (US intelligence sharing data with 4 of KC3's realms UK, Canada, Australia and New Zealand)
So as Head of the CIA you cannot roll your eyes and say that the info is from H&M, you have to pull agents from other important tasks to ensure that KC3's office is secure.
And the root cause of disruptions to vital national security functions is H's reckless behavior. Multiply the problem H created, via his proxy Omid, across all the various intelligence agencies across all sovereign nations as each nation wants to ensure any security and diplomatic information that crosses KC3's desk is secure.
IMHO, there is no PR solution to a national security problem. It is like giving a diabetes patient botox. Botox won't address the underlying issue, which if uncontrolled will result in even more severe issues for said diabetes patient.
