Except the previous thread really didn't promote any sort of discussion, it rather tried to avoid it
At any rate, nice to start anew with a general discussion thread about Islamic extremism.
So, let's move on with the points:
What do you think ISIL (or ISIS) is?
A terrorist group made up of Muslim fanatics. I don't think there is anything tricky or subtle here to be honest
How did they so quickly spread through Middle East
I have to admit, that I believe the US intervention in the Middle East really did play its part in the growth of such extremist groups. Meddling in the Middle Eastern affairs for year, with Iraq and Afghanistan for example, probably did channel the hatred of the people there for the west. Years of war, collateral damage and the like tends to cause civil unrest
Is Al Qaeeda as powerfull as it was a decade ago? Are they and ISIL connected in some way?
No, Al Qaeda is probably not as powerful as it was a decade ago. As for their connection, I think so. I heard that they declared war against each other about a year ago but this is not something I have been able to confirm. The different 'sects' of Islam have been feuding for centuries, so it should come as no surprise.
How do they get money for their actions?
Now that's a core matter. And it is the most suspicious one in my opinion. First let me mention the rumor of Turkey supporting and funding ISIS and its operations, which as of now is still a matter of discussion. Multiple oil trucks, whole convoys really have been going through Syria and the Middle East destined for ISIS. The question is, who provides the oil? How do they get it?
A similar scandal (among others) was discovered with Panama Papers. The massive petroleum supply to the Syrian Air Force through shell companies (to remove the trace obviously), despite the embargo declared by the US and the UK. It is highly possible in my opinion that similar methods may be used to fund ISIS and their terror operations, though in possibly a smaller scale.
Is CIA and NSA maybe hiding something about them? Do you think they secretly manipulate them?
Not just something...lots probably. There is a massive amount of data that gets declassified years after the operations and often excludes most of the details (which, remember, is where the devil is ). Given the shady history and background of such organizations and famous cases of whistleblowing concerning them directly (the latest of course being, Edward Snowden), it is highly likely that the CIA and the NSA has been dealing with such groups in secret for years. That of course, without exploring the rumor that Islamic State fighters and the Al Qaeda were actually trained and armed by the US
