Shannon Airport before and during the conflict, as were civilian aircraft transporting US military personnel; others had permission to overfly Irish air space. A resolution of the Dáil on 20 March 2003 approved these arrangements. Anti-war activist Edward Horgan took a case in the High Court seeking several declarations that the government, in allowing use of Shannon, had breached the state's obligations as a neutral state.

Days later the Department of Foreign Affairs said it would "constructively abstain" from an EU fund for military aid to Ukraine, by contributing instead to a parallel non-lethal aid fund. Weapons trade A 2004 report by Forfás noted that the policy of neutrality is a factor in Ireland's lack of an arms industry and strict export controls on weapons. The latter were previously enforced by the
