Nato must stand up to Putin

A Russian (who else could it be?) armed drone flies low over the border into Romania and smashes into the top floors of an apartment block exploding in a ball of flame and injuring two civilians. All Nato has said so far is that it will defend every inch of every alliance member. But actually, that's just words. Romania has been droned by Moscow and has got away with it. It could have been a misfiring by Russia but it looks far more likely to be a deliberate strike to see what Nato would do. Nothing it seems, so Putin will be very happy. Of course its tricky for Nato because they can't just fire off a drone or two at Russia in retaliation, but first and foremost that Russian drone should have been shot down before it reached the Romanian city of Galati, and then examined with great care to prove it was a Russian brand. And then Moscow should have been warned that if they do anything like this again, it will be regarded as an attack on the whole of Nato, and see if that gives Putin a reason to be more cautious next time.
