Cornered and humiliated by a now plausible military defeat, experts say the Kremlin could launch a tactical nuclear bomb on a Ukrainian site in a desperate attempt to turn the tables.

In any case, this is what Putin — who put Russia's nuclear forces on alert just after the start of the invasion in late February — is aiming to achieve: to terrorize populations in Western countries to push their leaders to let go of Ukraine.

Central to the tragic absurdity of this war is the question of language. Vladimir Putin has repeated that protecting ethnic Russians and the Russian-speaking populations of Ukraine was a driving motivation for his invasion.

Yet one month on, a quick look at the map shows that many of the worst-hit cities are those where Russian is the predominant language: Kharkiv, Odesa, Kherson.
