Also, it looks like once again, ISIS got blamed/framed for a mass killing it didn't commit. The 30 prostitutes in Baghdad were likely killed by Shi'a militias. They did the same in May, 2013. It is, however, unclear as of now who the gunman were as no one has taken credit. But the media has moved from their initial stories blaming ISIS to saying it's unclear.
Al Hayat Media has some new slick videos up: There's a really pitiful one of little blond kids from Bosnia who moved to Iraq, they hold guns and chant for Allah.
I still believe ISIS is giving no thought to the West -- they are establishing a state in the Middle East for all Muslims. In addition, since this is not an overnight battle, they have a lot of other stuff on their plate: setting up services, police stations, courts, collecting and distributing Zakat (sp), teaching classes on Sharia law and teaching kids to memorize the Quran. They also acquired a lot of military equipment and weapons -- tanks, rockets, missiles, etc-- that they need to store, transport and (probably) learn how to use. They are calling for Western recruits, especially professionals, doctors and engineers. They also are still doing some infighting and putting a lot of time into getting bayah from the tribes. They really don't have time to think about us unless we get in their way.
I think there's no hope for Iraq avoiding a split along sectarian lines. It will happen at some point. After Iraq, ISIS will go to Lebanon and Jordan next. So long as we don't go over there and start killing, it will be years, if ever, before they turn their attention to us. They perceive themselves as a state, not a terror group like al Qaeda.
As for Israel, so long as Hamas keeps firing rockets at them, it will continue to respond. Personally, I have no problem with Israel defending itself. Hamas wants to wipe out Israel while al Qaida (and ultimately every other terror group in that part of the world) wants to wipe out the Jews.
As to why ISIS isn't jumping in to help Gaza, here's one answer by ISIS follower AbuUmar8246 (who appears to be a researcher or religious student or teacher.) Of course no one speaks for ISIS except their official account, so you need to take what their supporters say with a grain of salt.
The ISIS position is that they want to consolidate their positions in Syria and Iraq before they move into Jordan and Lebanon. This is because it is well-known that fighting Israel in a full-scale war with proper weapons of war as ISIS have is not possible if they do not take over Jordan, and possibly Lebanon. This is because they need that land to transport their heavy weaponry such as their tanks, howitzers, hummers, APCs, bomb-making engineering workshops and associated machinery, and of course, their soldiers.
Its well-known however that Jordan and Lebanon are client states of America and that they have secret agreements with Israel to protect Israel from "terrorists", so any full-scale war on ISIS would be hampered by the Jordanian and Lebanese army attacking ISIS from behind. So it makes sense to get rid of those regimes first before fighting Israel face-to-face. And we know this will happen as the ahadith say we will fight the Dajjal in the Israeli city of Lod.
ISIS says it is recruiting foreign Muslims not to bomb, but to do nation-building in the newborn Khilafa. They aren't asking recruits to engage in random destruction or attacks on the West. They say they are different than al Qaeda that way.
It seems to me that so long as the tribes and ISIS work together out of necessity, despite their differences, they could plow through the rest of Iraq (except Baghdad) pretty quickly. I don't think ISIS ever intended to control Baghdad and make it their capital. I think they just want to destroy the Government there, and they will then make their capital elsewhere. At least that's what I read in a few of their missives somewhere.
One last thing: The news being put out by the Iraqi Special Forces has tended to be far more inaccurate than what ISIS puts outs. And ISIS has the photos and equipment to back up their claims. The worst is the lies by the Iraqis about the killing of prison inmates and claiming ISIS did it. They also exaggerate the number of ISIS attacks they have repelled and minimize ISIS wins. There's lots of independent journalists and analysts on Twitter and in other media who paint a different picture.
