Stan livedeath: bearing in mind most islamist terrorists in the UK are " home grown", can anyone tell me what they are trying to achieve ?
It doesn't seem anyone answered Stan's question. This is also what I struggle to understand.
Some terror campaigns are successful in persuading an occupier of a region to leave, or a minority in a region to leave where that minority has somewhere else to go. There is no hope of this terror campaign achieving anything like that. It can only harden resolve against the terrorists.
If there is any logic to why they do it (beyond the logic of the individual who believes he is going to get rewards in heaven), I think it is more a political statement to the world, that they exist and that they are powerful and frightening.
As for the answer? I don't have a simple one at the moment. A lot of terrorist movements in the past have eventually just petered out. For example, in the 1970's there were a few Marxist terror groups around, all of who have disappeared, and some Arab nationalist terror groups that disappeared. (The only ones that lasted were ones that were also acting like mafia, using their network make financial gain.) So maybe continued thorough law enforcement will wear it down; I don't know.
The other thing I notice is that virtually all recent Islamist terror seems to be from one sect of one branch of Islam. The second biggest branch of Islam (Shia) is every bit as anti-ISIS as the west is. Same could be said for other groups (Ibadi, Kurdish, etc). It is worth bearing that in mind.
