The Kremlin believes that there is, in some way, Ukrainian responsibility for the terrible attack on the Crocus City Hall in Moscow. The claim of ISIS seems to count for little in the eyes of the Tsar who, however, is well aware of the Islamic terrorism of Caucasian origin which has already struck in Russia in recent years.

Some observers breathed a sigh of relief at the news of ISIS's claim. The EU's concreteness and timeliness should now be the EU's watchwords. The world is changing very quickly and the construction of a true and concrete foreign policy must be the strategic priority of the 27.
