Putin’s Russia is a threat to all Europe, including the UK. Vital aid work will be hit as we spend more on defence, but we must deal with the world as it is

There are moments in history when everything turns, but the extent of change is not perceived until later when the fog has cleared. These are hinge points that require clear leadership and bold action. In the late 1940s, my Labour predecessor and hero Ernie Bevin, alongside Clement Attlee, saw through the fog when they led Britain into Nato and the UN, and secured the development of Britain’s nuclear deterrent. In the 1960s, Harold Wilson saw through the paranoia of the cold war, refusing Lyndon Johnson’s request to send British troops to Vietnam. In the 1990s, Tony Blair understood that unless we stopped the president of Serbia, Slobodan Milošević, there would be no peace in the Balkans.

Three years into Vladimir Putin’s brutal war, this is again a hinge point for Britain. Keir Starmer’s commitment to dramatically raise defence spending in both this and the next parliament shows his leadership through the fog. Putin’s Russia is a threat not only to Ukraine and its neighbours, but to all of Europe, including the UK. Over successive administrations, our closest ally, the US, has turned increasingly towards the Indo-Pacific, and it is understandably calling for Nato’s European members to shoulder more of the burden for our continent’s security. Around the world, the threats are multiplying: from traditional warfare to hybrid threats and cyber-attacks.
