The United Nations has a veto on any Irish military action thanks to the 'triple-lock' (must be approved by the government, the Dail and the UN). This is the UN that slyly associated a fellow EU member, Denmark, with racism in its anti-racism poster.
Obviously the government must approve any military action and the requirement that the Dail also approve is fine with me. But, why should any other power have the say-so? And, if there must be a 'grander' body that approves military action, shouldn't that be the EU?
