The ONLY thing I would say to all that is that the IRA actually existed, and civilians were constantly attacked by them, for over 30 years. The IRA even managed to blow up the UK government. The threat was real. IMHO, the AQ threat is 99% bogus. It all hangs on 9/11, and the London Underground bombings. One single event in the US, then the UK. Yes I know other events have been attributed to AQ, but frankly, one by one, they all fall down as actual organised terrorist activity. Its mostly pissed off people aligning themselves with Islam or AQ. Frankly, now journalist's partners are considered a threat to national security and arrested as terrorists, we can see how lose and there for useless the term "terrorism" now is. Its is not even slightly the same as the IRA. They were "proper" terrorists.
There for, one can understand (note: not condone, excuse, etc) the extreme reaction of the UK government. Although, for all that time, the US was funding the IRA. So........er.......
- Large scale arrests and imprisonment without trial - "internment"
- Massacres of innocent civilians by British Army soldiers - Bloody Sunday
- Officially supported interrogation techniques that bordered on torture - the "Five techniques"
- Innocent people forced into admitting that they committed terrorist acts, convicted and given long jail sentences - the Guildford Four
