Ukraine - to intervene or not to intervene.

President Putin insists that he has no intention of invading Ukraine. In amassing troops and weapons along the border, the Russians are merely ‘protecting their national interests’. Meanwhile NATO, the US-European military alliance, is busy reinforcing its eastern member states with ships and planes. Our own Prime Minister has issued dire warnings that Russia will not be allowed to harass a smaller neighbour in this way. So, who is right? Is there a moral imperative for us to protect a fledgling democracy that seems to be under threat? What, if anything, can we – or should we – do to support Ukraine? And what moral arguments do we have, to help us decide? Perhaps this is just aggressive posing by both sides that will drift on and die down. But what if it becomes something more? What if it embroils us in a European war? And if that happens, who will be to blame? Given the record of the UK and the West in Afghanistan and Iraq, do we even have the appetite for another foreign intervention? Is the very idea morally dubious? And, in any case, doesn’t the size of Russia’s nuclear arsenal make it impossible for us to call Putin’s bluff?
