Simon:
The mistake you are making is to take "no massive attack ... yet" as being evidence that "there can be no massive attack ... ever".
Well, I believe no such thing.
Please! You have called me out for reading things into your posts, now you are doing that to me.
Obviously this shows how important it is to place extra surveillance on more competent Jihadis such as those who will be returning to the UK after the Islamic state finally fails as they have real weapons training and know how to make bombs.
I don't agree with Muslim Mayor of London that "oh well, you just have to accept it".
I only think that is true in the same sense we have to accept pedophilia.
