Jim there has been a lot of information released about American interference in other countries as you say. This has been caused presumably by American Presidents although to what extent they are constrained or even nudged by external forces is unknown. Eisenhower was very clear about the military industrial complex and as time has gone by I would be surprised if that influence has diminished- so it rather begs the question-Who actually runs the show.
As we all know what a politician says prior to an election manages to mutate into a very different beast once in power. I am sure the same constraints apply in other countries (UK)as well. We have two prime examples of a referendum and election going against all predictions.
How much of what we are reading about the President elect is merely the machinations of extremely sore losers trying to delegitimise his presidency before it has started. Interestingly certain British newspapers just will not drop the subject even though so far not a single shred of evidence has been offered to support the allegations.
To hope Trump may be overthrown or deposed could cause any number of unintended and intended consequences and those events would not just be internal to the States. You should be very careful of what you wish for.
I find both the American election and Brexit vote surreal. I just hope it is only the bookmakers with tears
