If this wasn’t a national security issue fir the UK before, it is now.
And why hasn’t the US kicked the man doing this out of the country?
In the U.S. pre-Clinton, the State Department would have stepped in to remedy this security risk, negotiating with UK and the "adorable couple" to reach an understanding such as the one that Britain arrived at with the Nazi-sympathizing King Edward Simpson.
It's probable that the same individuals and their minions who stuffed the State Department with leftists, and the one in particular who has demonstrated contempt for Britain and who also handles Biden, are part of a network of advisors behind H&M's anti-monarchy screeds. H&M have become tools of the deep state.
