We could get into the semantics here, Big Mick. In my view (as no doubt, in yours too), the US should not be responsible for our foreign policy. In a moral sense, it certainly is not. Unfortunately, the evidence of my eyes has been that barely a major decision is made without the rubber stamp of whichever President is in office at the time. The only exception I can recall, was Harold Wilson's refusal to enter the Viet Nam War. I don't spend my days and nights studying political and financial columns, so I am not aware of the exact details of US investment in our country or UK investment in yours. I know that both figures are substantial though. I suspect that has something to do with it.
I did not intend my comment to sound anti American. I think you can be very pro American while retaining a very low regard for your current President!
