Task to the film "the imitation game"

task 6.  Why do you think British Secret Service erased all traces of Turing's machine after the war was won?

Why they erased all traces of the machines existents is because they didn’t want the world to know that they had broken a code that supposedly was unbreakable. I think that they did this so that if the time came, where they had to break another code they could do so by making another machine.
