Finally, the order to kill might have come directly from the ISIS central leadership. In this case, it can be viewed as a demonstration by extremists of their intention to continue on the path of escalation. If this is true, then the increasing ruthlessness displayed by ISIL can be seen as a way to compensate for internal tensions (acts of desertion by some ISIS members and inter-ethnic conflicts between some factions). It can also be viewed as a warning to the members of the anti-terrorist coalition, which have been promising a stronger response for months. With this attack, ISIL is in effect telling them that a new counterterrorist operation will trigger an extremely violent asymmetrical response.

I believe that in light of the situation, the Egyptian President, Abdel Fattah al-Sisi, has made the only possible right decision by ordering a swift, and apparently effective, strike against the terrorists. This decision essentially demonstrated to the rest of ISIS’s opponents the right course of action.

Of course, the ISIS cannot be defeated through military strikes only. The Islamic State is just the tip of the radical Islamist iceberg, which is firmly entrenched in the Muslim world. But the show of force by the Egyptian president, the show of audacity even—after all, he still remembers President Anwar Sadat’ killing by Islamists in 1981—is actually very important.

The theatricality of the Sirte massacre is also worth mention. Ironically, excessive theatricality and even pomp is what the ISIS “caliph,” Abu Bakr al-Baghdadi, had been accusing Al Qaeda of until recently, while extolling the pragmatism of his own organization. But, after Sirte, who can vouch for the fact that ISIL is not going to adopt Osama bin Laden’s notorious methods and organize a September-11-scale terror attack? If this is in their plans, security services around the world should redouble or even triple their vigilance.

The Islamic State has created a relatively stable organizational structure and controls vast swaths of land (100,000 square kilometers, according to some estimates). It is generally agreed that in terms of its reach and the number of fighters under its banners, ISIS has outstripped Al Qaeda, essentially becoming the first transnational Islamic state. Just like Al Qaeda, ISIS attempts to act on the global scale; it seeks to embrace almost the entire Muslim world, including Central Asia and the Russian North Caucasus. At this point, ISIS doesn’t stand much of a chance in the post-Soviet states, although some experts believe that this may change, and the organization has already started to plant its cells in the Russian North Caucasus.

But ISIS can be far more successful and no less inhuman in other countries and territories—for instance, in Africa, Yemen, and beyond.
