Well as an Arab I do agree with iTpHo3Nix and Darkvision,
since yes the arabs are generally very dumb, not dumber than most murican's, but atleast murican's aren't blowing up shit everywhere, but history has proven that they can be manipulated quite easily.
If you want to nuke them go ahead, but stay far from lebanon or wait until I get the hell out of here, but we all know "nuking" is a rather "controversial" way to deal with the problem.
When it comes to Anonyshit, hacking into their twitter accounts, may cut a bit of the recruiting but these have magazines in multiple languages and websites, in france facebook is a widespread way to recruit and communicate, since most of the guys joining ISIS are stupid kids spending their time on facebook that everntually got manipulated, but a french journalist made a fake account acting as a women who wants to go to syria and marry a "mujahid", 2 days later she has 200 friends half of them already in Syria and the other half intending to go there. The problem there is that it's a known fact is that it's very easy for a gov to shtdown fb accounts, especially when it's about terrorism and the banner + feed of these guys are mainly ISIS propaganda. I could do a script to identify all the ISIS account for god's sake
