TL;DR:
US: Jump!
UK: How high?
[Rinse and repeat ad nauseam]
It never begins to amaze me how the UK is so much America's lickspittle that successive British governments are literally willing to sabotage their own economy & security, just to please their American masters. These are the same people who, seemingly without a trace of irony, spout phrases like "Taking back control", in relation to leaving the EU.
