The Islamic youth of Britain, or at least enough of them, are dissaffected...many may be educated but that is just one part of the issue....you're right though. It's no real challenge for people of a certain 'talent' to wind up young men who feel a bit angry about this or that and turn a very few into terror bombers...so in that sense yes it is a Muslim community problem on one level.
Unfortunately the violence in Spain last year actually succeeded...changed the govt of the day and the incoming govt changed their foriegn policy. That has bolstered the fundamentalists...if they ever get the Brits or Yanks..or heaven forbid the Australian Govt to base the foriegn policies on 'what the Islamists think might be ok' we are ALL well and truly fecked....on that level it is our problem.
Yes the Islamists want a world wide Islamic Kalifat based around Sharia...but do you think they have told the grunt labour that?
What I find interesting about this latest drama here in London is the 'system' actually worked and stopped them/caught them...but still the mayhem at the airports?
I find it a little hard to work out why they would try and sneak explosives onto aircraft at LHR...when it would be so easy to smuggle a dozen MANPADS into SE England and sit in a tree copse in the middle of an otherwise empty field within 5nm of LHR, Gatwick, Stansted or Manchester and simply shoot down airliners as they file past between 4000 and 8000' on arrival/departure...a much more powerful statement than 3 or 4 widebodies blowing up over the Atlantic out of view.
