Two real SME on the situation. One, Dr. Omar Ashour, now @ Exeter University, I always listen to. Here he is interviewed by Voice of Russia Today, with two others from UK Muslim groups, and provides the context for what we see today. There is a podcast and transcript:http://voiceofrussia.com/uk/news/201...ic-jihad-2074/

Here is one passage:
In terms of ideology it’s sort of interesting because the Islamic State is a fringe of a fringe. So, al-Qaeda is a fringe and it took even more extreme twist in a sense that they are using excommunication declaring others as infidels and apostates in a much wider way than al-Qaeda does.
On intervention in Iraq, with some poignant pre-conditions:
The problem is very complex. There is ISIS and there is a threat, but ISIS are there because of certain reasons and some of them have to do with how the Arab Sunni population was treated in the last few years mainly by the al-Maliki government in the aftermath of the US withdrawal and the US invasion in 2003 as well. Unless these core issues are resolved and unless you find an Iraqi elite that is willing on one hand to unite against this threat, and on the other hand, is willing to accept intervention to end it, and you have a population that is revolting against the Islamic State […] Unless you have these conditions then I don’t think an intervention would be quite successful. Maybe it will undermine it or set it back a bit but then the environment, if you have this level of oppression and this level of brutality and lack of freedom, ethnic groups and religious groups who are marginalised and repressed, then you create an environment where the Islamic State or other groups will emerge just as violent and extreme.
Secondly there's Clint Watts (CWOT on SWC) in a long interview on CSPAN's Washington Journal, which I have yet to listen to:http://www.c-span.org/video/?321100-...-response-isis
