Remember when they kept on telling us about how effective the tanks would be on the battlefield? Or how ineffective the Russian defences would be once the counter offensive started? Or that Ukraine would be supported for 'as long as it takes'? Do you still believe NATO would defend every inch of NATO territory?
By the time the Russians get around to invading NATO they will have massively expanded their military industry, learned and honed all the new warfare tricks and probably emboldened Iran and China to help out this time, because the west are proving to be basically unreliable pushovers. When the action inevitably starts, will we have built up military resources just in case? I doubt it.
