"We are seeing the return of industrial warfare to Europe" - Professor Michael Clarke

"We didn't think we would see it after 1945, but it is back with us again now. The war is won by the side who can gear up its industry to fight a long campaign in what is a war of attrition.", he stated.

"The EU has delivered economic support, keeping the [Ukrainian] government running. The US has delivered the military support. The US can't deliver more ammunition without agreement in congress."

"Ukraine is the crucible for the ability of the western democracies to push back against the tide of autocracy which seems to be taking over the world"

"If the western word is seen to be a paper tiger, to not be able to deliver on its commitment, the rest of the world will take due notice of that and begin to lean towards Putin and Xi Jinping in China and other dictators on the assumption that the world is now moving in their direction."
