Crisis in Ukraine - Iron curtain made real once again

It is an indication of the ruthlessness, not by any means used for the first time, that Russia is prepared to deploy to maintain a cordon sanitaire between itself and western Europe, the source of catastrophe after catastrophe for Russia over the last two centuries. Those centuries’ apocalyptic invasions cost almost 50m Russian lives and ensure that Putin’s interventions in eastern Europe — and probably those of his successors for generations to come — have the support of a great number of Russians.
This world view is not incomprehensible, especially as Russia’s citizens are also denied the freedoms some of Ukraine’s 45m citizens exercised by trying to strengthen links with the EU rather than Russia, an entirely valid choice at the root of the escalating violence in Kiev.
