Sqwk, much of the anti-western feeling in the Arab world originates in envy, I agree.
However the motives of the terrorists go far deeper. Envy doesn't make somebody take their own life for a cause, however misguided that is. From my observation certain 'belief systems' lend themselves to being misused for this purpose. That's not to say those systems are wrong....
Recent surveys in the UK have revealed much similar views amongst certain parts of the population to those in Canada.
All a bit off topic....
