Sometimes, states that are close allies, for reasons of history, culture and politics, can disagree over whether or not members of a certain organization are terrorists. For instance, for many years, some branches of the United States government refused to label members of the Provisional Irish Republican Army (IRA) as terrorists while the IRA was using methods against one of the United States' closest allies (the United Kingdom) that the UK branded as terrorism. This was highlighted by the "Quinn v. Robinson" case.
