I don't condone what these people have done - but I am sympathetic to their protest. I think that the use of armed drones undermines the status and virtues of military service. If I read about a successful UK manned operation I always feel a sense of admiration for those involved, and a sense of pride that I was once part of that service. Whenever I read about a successful drone operation, I feel no sense of pride or admiration at all - indeed the contrary. I fear that over use of armed drones will in the long term erode the public's regard for our military services.
