At least the BBC had the decency not to air the raucous affair of Brits beating Brits over the visit of an American, but it was well covered by our press here in the states. So much foreign policy is out on the internet these days and the online commenting, speculation and interpretation of government policies by 3rd rate internet trolls and social media experts is generally where the lazy media get their (inaccurate) information. There are some real questions going on with Brexit that don't concern the US per se and that should be determined by the Brits, obviously the timing (not a State visit though) was awkward to say the least. It would appear both Merkle and May both are going to have a tough road holding onto power and control of their governments for reasons not pertaining to President Trump. Another reason that this trip might have been better at another time. I understand we were in trade negotiation with the UK and the US had some concerns about the EU continuing commitment to Russian energy considering NATO spends a lot of money supposedly protecting Europe from Russia. The whole deal with Gerhardt Schroeder and a Russian energy company looks really horrible, as does the migrant issue with all EU nation, coupled with England's possible exit from the EU and other disagreements within the Union, it is quite the sticky wicket as you chaps say.
Yes, I would have been horrified had Americans floated a blimp of the Queen or other foreign leader. This is not how adults act and I think that is the real root of many problems today. At this point more and more people are leaning toward Trump in the upcoming elections, both by proxy in congress and in the next Presidential race. Those people are not bad or hateful people, they are just sick of corrupt and ineffective leaders
