No, they just tried to kill Prime Minister Thatcher and over half of the House of Commons in Brighton.
My point is that Sinky is attempting to make a preposterous analogy, which there is no evidence to support.
We are at war with entrenched, revanchist Islam.
We are not are war with ETA, or the ETTE, or the IRA, or the UDA, KDP, or any of a number of equally loathsome terrorist organizations that we would all prefer not exist.
The people who are plotting to kill us are almost without except Muslims.
They worship Mohammad, they read from the Koran, and they attend Masjids.
Even if I were to concede that the IRA was animated by religious motivations, Sink's comparison would still be inapt, because there are not hundreds of comparable groups peppered throughout the globe.
