Well our ambitions were never really to develop and retain our own bomb as the costs were prohibitive for a bankrupt Britain…we just needed to demonstrate our ability to get a bomb so the Yanks could sell us an off the shelf system and we become a significant part of NATO. The bomb was just the tool to access the club and get us to a seat of power around the table. Without it we would have been edged out, but instead we were an instrumental part in fighting, and ultimately ending, the Cold War.
americans were holding onto their technology and weren’t going to help us out with our bomb.
All’s fair in love and war and global politics. We kept the Americans out of our intelligence and code breaking abilities through the war and played the Americans as and when it suited us, so we’re just as devious when we need to be.
