Bombs, Bullets and the Border examines Irish Government Security Policy and the role played by the Gardaí and Irish Army along the Northern Irish border during some of the worst years of the Troubles. Mulroe knits together an impressive range of sources to delve into the murky world occupied by paramilitaries and those policing the border. The ways in which security forces under Fianna Fáil and Fine Gael governments secretly cooperated with the British Army and the RUC, exacerbating tensions with republican groups in the border counties, are meticulously examined. Mulroe also reveals the devastating consequences of this approach, which left a loyalist threat unheeded and the 26 counties open to attack.The findings of the Smithwick Tribunal and the upheaval of Brexit have kept the issue of Irish border security within the public eye, but without a complete awareness of its consequences. Bombs, Bullets and the Border is vital reading in understanding what a secure border entails, and how it affects the lives of those living within its hinterland.
