From all account the bombing were done by UK citizens who were muslim extremists.
The iraq war is a reason for it, but it has been brewing for a long time. Asian communities live in "Ghetto" like areas, alienating themselves from local culture.
By not adapting to local culture and living by their own agendas alienates them form british culture.
If u move to another nation, u should try and adapt to the new cultures.
Oftne these muslims groups fail to do so.
I am of part iranian origin, and have witnessed muslim groups alientate themselves. In doing so they have often become ngry with british culture fueling hatred for western ways which conflict with thier beliefs.
Breaking up these ghetto's and allowing the muslim culture to properly integrate into modern british society will go a long way in reducing problems such as home grown islamic extremists, but also help provide other non-muslim social groups a better understanding.
