In this revealing and fascinating account, the impact of the Provisional IRA's bombing campaign in Britain on both British government policy towards Northern Ireland and the internal politics of the republican movement, are examined in detail. The book highlights the early thinking of the British government and draws on recently released public records from 1939, 1973 and 1974. It makes extensive use of television documentary footage to offer a broader analysis. The book also examines republican rationale behind the campaign, the reasoning behind the use of particular tactics and the thinking behind atrocities, such as the Birmingham bombings. Using a range of new evidence, the book highlights the bankruptcy of republican strategic thinking and challenges the notion that successive British governments appeased republicans because of the threat of bombs in London. The analysis of the campaign is placed within the wider context of the ongoing violence in Northern Ireland as well as the history of republican violence in England dating back to the nineteenth century.
