At a drop of a hat, western leaders are absolved of guilt or even responsibility for the terrible events that unfold. The West remains virtuous, simply a victim of the world's madmen. Nothing the West did was a provocation. Nothing they could have done would have averted the disaster.

The US may be the most powerful state on the planet by far, but its hands are apparently always tied by a deranged, implacable foe like Russia's Vladimir Putin.

Putin, we are told, is not advancing any rational – from his perspective – geopolitical or strategic interest by invading his neighbor, Ukraine. And so no concession could or should have been made because none would have prevented him from acting as he has.

The West, meaning foreign policy hawks in Washington, gets to decide when the timeline of events started, when the original sin occurred. The compliant western media give their blessing, and our hands are washed clean once again.

The subtext – always the subtext – is that something must be done to stop the "madman". And because he is irrational and a megalomaniac, such action must never be framed in terms of concessions or compromise – that would be appeasement, after all. If every enemy is a new Hitler, no western leader will risk a comparison with Neville Chamberlain.

Instead, what is needed urgently, western politicians and media agree, is the projection – whether overtly or covertly – of yet more western power and force.
