In response to successive terror attacks on Britain, Prime Minister Theresa May said that things could not continue as they were. By “things” she meant the systems set up by democracies, particularly Britain, to prevent atrocities like those experienced recently in Manchester and at London Bridge. The systems of defence have proven inadequate.
It seems likely that many people, in many countries, agree with her. We must somehow avoid letting these crimes by fanatic jihadis become so frequent that we view them as more or less normal. Few will be willing to settle for the insouciant view of London’s mayor, Sadiq Khan, that terrorist attacks are now “part and parcel of living in a big city.”
