Britain’s political class did not distinguish itself in its immediate response to the Crimean crisis. A zoom lens outside Downing Street which captured Cabinet Office papers in the hands of an unguarded official seemed to reveal yet more evidence that the protection of the City trumps any other strategic instincts for this government. Labour, meanwhile, appeared to be more rattled by Tory Twitter jibes than by Vladimir Putin’s machinations. But the challenge posed by Moscow’s intervention in Ukraine will outlast any initial inclinations to see it through the prism of the Square Mile or the Westminster bubble. From the future of the European Union to UK defence priorities, Russia now presents a number of long-term dilemmas for progressives, regardless of how the events of the next few months play out.
