Jean de Gliniasty: “Western solidarity goes to the Russian people, not to the authorities”. The attack in a concert hall in the suburbs of Moscow is the deadliest in Russia since 1999.

Initially, the violence and cruelty of the attack will strengthen the solidarity of Russians around the leader, as has been observed everywhere else in similar circumstances. But then power will have to be held accountable, in one form or another. Does this attack risk accelerating Russian military engagement in Ukraine? The fact that the Kremlin did not cite the Daesh press release, and that the terrorists' attempt to flee to Ukraine was highlighted by the head of state, seems to indicate that it will be used to strengthen exceptional measures.
