I don’t know what warped logic drove Putin to blow up a stationary Ukrainian locomotive on the Polish border this morning. What we can say for sure is that this is the kind of random and senseless attack Ukrainians are enduring every day - even on civilian railways. So far Putin has been responsible for the deaths of 1700 staff of Ukrzaliznytsia - Ukrainian Railways. They and their daily passengers are absolutely heroic. When are we going to give them the air defences they need? Why won’t we unfreeze Putin’s cash and give it to Ukraine? There is more than €140 billion in a Belgian bank account - and about £10 billion in London. Britain could show a lead. The Ukrainians are going to win - that much was clear from the last three days in their wonderful country. But we will get this dreadful war over much faster if we all get serious and give them what they need and deserve.
