‘We must stop using the language of force and return to the path of civilized diplomatic and political settlement.’ So wrote Vladimir Putin in The New York Times in September last year. Last week, he invaded Ukraine. A system of ‘international law’ which gives a man like President Putin the right to decide whether a proposed action is legal or not, is morally bankrupt. Yet that is how the United Nations Security Council functions – and that is why Western democracies should not shrink from taking action even when the Russian veto stands in the way. President Putin’s New York Times piece was about Syria. He was appealing to the American public not to assist Bashar al-Assad’s opponents. Assad has used barrel bombs to cause indiscriminate death among civilians, has enforced starvation sieges on Syrian cities, and has sent out his forces with orders to arrest, torture and kill his opponents.
