most of the other terrorist outfits u named are for economic reasons..they are about people being poor ,not able to earn and work etc etc...
But this islamic terrorism is such that people get into it for religious reasons.. In the name of god they become terrorists, of course some are economically backward, but this backwardness is caused by their own religion which s against condoms abortions and encourages polygamy too,they have large familes even when they cant feed everyone(every muslim thinks he is a nawab to feed 10 children i guess),now when it gets tough to feed everyone ,how will they educate them etc ...most of them dropout of school very early and start working or doing petty crimes.. this is when the Islamic terrorist sponsors take over by providing for basic necessities and brain washing them...
