M - Z

Christopher Andrew, Defend the Realm (2009), p. 605, calls O'Halpin "the leading historian of Irish security."

O'Halpin, Eunan. "'A poor thing but our own': The Joint Intelligence Committee and Ireland, 1965-72." Intelligence and National Security 23, no. 5 (Oct. 2008): 658-680.

The author concludes that "where Ireland was concerned the JIC system failed on several counts.... [T]he remarkable feature of the JIC's record in the years leading up to the outbreak of the Troubles is not how few but how many red herrings it pursued."

O'Halpin, Eunan. "Small States and Big Secrets: Understanding Sigint Cooperation between Unequal Powers during the Second World War." Intelligence and National Security 17, no. 3 (Autumn 2002): 1-16.

Peake, Studies 54.3 (Sep. 2010) and Intelligencer 18.1 (Fall-Winter 2010), notes that the author studies "the intelligence relationship between [Irish] G-2 and [British] MI5-MI6," and explains, "in considerable detail, how it fit the political realities of wartime Ireland." This "is a very valuable contribution to the history of WWII intelligence." For White and Riley, Irish Studies in International Affairs 19 (2008), O'Halpin "highlights the intelligence cooperation between Ireland and Britain during the war" and emphasizes "the assistance the Irish government provided to the Allies."

SOE plans for a stay-behind operation in Ireland, as well for a rumor-planting campaign, ran afoul of both MI5 and MI6 -- and of Churchill's reluctance to provide arms to the Irish.

Doerries, JIH 9.1 & 2 (Summer 2010), notes that "[t]he 'Official History' presented in this highly interesting volume is, in fact, the history of the Irish Section [BIH] of MI5. The document ... was produced between the autumn of 1944 and the early days of 1946.... Eunan O'Halpin provides an excellent introduction for the contemporary historian as well as for future researchers possibly less informed on the internal makings of British intelligence in the 20th century.... [M]uch of this 'Note on the Work' is about: the fruitful cooperation of Irish and British intelligence [against the Germans] during World War II."

According to Peake, Studies 52.1 (Mar. 2008) and Intelligencer 16.1 (Spring 2008), seven of the 15 articles presented here "discuss the history of Irish intelligence over four centuries.... The broad historical perspective ... on what works and what does not in intelligence will be of value to students of the profession as they search for answers to today's intelligence problems." Skelly, IJI&C 21.4 (Winter 2008-2009), finds that "[w]hile this collection's assessment of intelligence in Ireland is timely, an added benefit is its comparative framework.... Another advantage is its extended timeframe."
