The first option is that they continue to expand the borders of the Caliphate throughout the region until economic or military limitations stop them and they afterwards consolidate their positions. Too bad for the West, it doesn’t look like such limitations exist for the Caliphate.
The second option is that they goad the West into launching an all-out ground attack, thereby setting the scene for the final battle between Muslims and the crusaders prophesized to be held at Dābiq in Syria, by conducting an operation overseas that is so destructive that America and its allies will have no alternative but to send in an army. This would have to be something on the same scale, if not bigger, than 9/11. Then again, I’m just guessing. American “hawks” may very well come to Dābiq on their own without the Islamic State needing to blow up any dirty bombs in Manhattan.
Back to the rest of the magazine: The reason for downing the Russian plane:
This was to show the Russians and whoever allies with them that they will have no safety in the lands and airspace of the Muslims, that their daily killing of dozens in Shām through their airstrikes will only bring them calamities, and that just as they kill, they will be killed, by Allah’s permission.
They say they compromised the security at the airport and smuggled the bomb on board:
[A]fter having discovered a way to compromise the security at the Sharm el-Sheikh International Airport and resolving to bring down a plane belonging to a nation in the American-led Western coalition against the Islamic State, the target was changed to a Russian plane. A bomb was smuggled onto the airplane, leading to the deaths of 219 Russians and 5 other crusaders only a month after Russia’s thoughtless decision.
The description of the attack on France: Only 8 attackers, not 9 and again, the motive was retaliation for airstrikes.
On Friday, the 1st of Safar, 8 soldiers of the Khilāfah carried out an operation in the heart of French crusader territory. The operation involved multiple simultaneous attacks with explosive belts and assault rifles on various targets including the Stade de France stadium, where the crusader president Francois Hollande was attending a soccer match, and the Bataclan theatre for exhibitions, where hundreds of French mushrikīn had gathered for a music concert.
The attacks, which included other targets around Paris and succeeded in killing hundreds of crusaders and wounding even more, shook the world and reminded the nations of kufr that the Islamic State will continue to stand firm in the face
of their transgressions and retaliate with fire and bloodshed in revenge for the honor of the Prophet g and the multitudes killed and injured in crusader airstrikes in the lands of the Muslims.
