Seán Russell, the IRA, and the German-American Bund
According to Irish republican Tom Barry, who from all indications served honorably in the Irish Army's Military Intelligence during WW2, IRA leader Seán Russell who collaborated with Nazi Germany, got his funding from the German-American Bund, a pro-Nazi American group
"In October 1936 Russell wrote to the Nazi ambassador in Washington, offering IRA support in any future conflict between Germany and Britain. Indeed the promise of German financial and military aid was key to Russell winning control of the IRA. One of his rivals for the IRA leadership, Tom Barry, claimed that the German-American Bund, the main Nazi organization in America, funded Russell’s campaign."
