I stand by the general conclusion that the majority of terrorists of origins in Islamic societies are religiously motivated. They are motivated towards violence as a way of as they see it defending their religion rather becoming clerics or missionaries or whatever because there is is an aspect of their religion which already denies very significant rights to religiously specified groups.
In Abedi's case, his sister asserts he wished to extract revenge for US military strikes in the Middle East, specifically those which had killed children. This is a political statement. But as we know that a high proportion of Muslims regard any attack on a Muslim country as an attack on the religion also, and that the duty of other Muslims is to bond together in opposition to such attacks, then we have to conclude there might well have been a religious element in what he did. In any case, in view of the evidence from other terrorist attacks and plots, if we wish to understand the problem, ignoring the religious element is blinkered and therefore dangerous.
Its is true that only a tiny percentage of Muslims commit terrorist acts, However, in the respected Channel 4 survey, 90% of Muslim respondents condemned terrorism. It should ideally have been 100%, but as it turns out, 90% is higher than amongst the UK population as a whole. Nevertheless, it is predominantly persons of Muslim origin who actually move on the acts of terrorism in the current political context. I still say this is due to a pre-disposing aspect of their religion as opposed to others.
As I said we are all free to believe what ever we like even with your ifs and buts when those closest to the terrorist outline the reasons behind his actions.
fwiw - He was reported by the muslim community. Who ever did the reporting would obviously like to remain anonymous. You have to remember Pakistanis and Libyan's not exactly of the same tribe.
Apparently, border police let him in despite his trip to Libya, Syria and return back to Manchester via Turkey and then Dusseldorf.
I would simply refuse entry to such people or bring them in for questioning and then send them back.
I can't imagine what justification this terrorist tit would have had for those trips. We must tighten up our border controls, customs and rules for entry that's for sure.
