AOG - "It is time the authorities thought up new ways of punishing these terrorists when caught and convicted, it is no good executing them because they obviously do not fear death.
And locking them up for life is not the answer, perhaps punishing them through their religion might be the answer, such as a life sentence working in a pig farm, that might scare the hell out of them?"
Why do you persist in viewing other races as some kind of inferior life-form that are 'ours' to punish as we wish?
The extremists that perpetrate these evils against The West perceive us as arrogant war mongers who think they world should bow down to democracy because we think it's a good idea. They hate us with a venom that we can't even imagine. They will never ever stop if simple military battering, and 'punishments' are what they receive from us.
Dialogue and education is the way forward.
We should be talking to Al Quaida about our differences and stressing that we are not keen to enforce an alien way of life onto their people simply because we feel they need it.
If we can learn to co-exist without hatred and fear, then we can end terrorism, but it thrives on ignorance and force - the very ideas that you put forward as solutions.
A little repsect for others' ways of life that are different from ours will go a long way towards stopping violence, and from there, we may even pursuade the Muslim community that some of our ideas and lifestyle may be good for them, but we simply cannot force people to live like we do, it is arrogant, and it ends in violence and terrorism.
We should have learned from Viet Nam - we didn't - so when we realise that military action and scare tactics are not the way forward, and that compromise and dialogue are the only solution, we can start to get somewhere.
Sadly AOG, more people who think like you than I are in positions of power in Western governments, so I do not expect to see any peace in my lifetime.
