Recorded at the Battle of Ideas festival 2025 on Saturday 18 October at Church House and the Abbey Centre, Westminster. ORIGINAL INTRODUCTION The past year has seen a flurry of announcements about military investment in Western countries. Following Trump’s re-election, and his blunt demand that European countries invest more in their militaries, the EU announced €800 million of funds for defence in a package called ReArm Europe (later renamed Readiness 2030 after backlash that the package sounded too militaristic). NATO members then agreed to bump defence spending to five per cent of GDP – although some, like Spain, secured opt-outs, and members will be able to count certain infrastructure spending towards the target. Aside from Trump, the calalyst has been Russia’s invasion of Ukraine and a more uncertain and dangerous geopolitical situation around the world. From clashes between India and Pakistan to continuing war in Gaza, threats from China about Taiwan, instability in the Balkans and rising tensions in South America – few deny the world is a more unstable place than it was a decade ago. The question is how Western countries should respond. Many suggest that the new period of rearmament is a necessary corrective to a longstanding vacation from geopolitical realities. In recent decades, weapons stockpiles have shrunk, armed forces have been reduced and industrial capacity has declined – to the point where few Western countries except America or Poland could sustain a serious conflict, or even a minor one. While Western states have let military spending fall down the list of priorities, newly emboldened countries like China, Turkey, the Gulf States and India have grown their armed forces. But others worry this new talk of militarism risks fanning the embers it is supposed to contain. Some joke that it could be dangerous for Germany, which has spent the postwar years being told to constrain its military, to now be encouraged to spend hundreds of billions of euros on its armed forces. Newly furnished militaries could be like Chekov’s Gun – just waiting to go off. Others point to the loss of progress on arms-reduction treaties, or the dangerous rhetoric of civilisational competition. Burgeoning social-welfare commitments, skyrocketing energy prices, decades of infrastructure decay, and a lack of critical raw materials make rearmament more difficult than simply declaring a new target. But perhaps the most biting criticism is the gap between these new military ambitions and the reality at home. Western countries cannot defend their borders against illegal migration, let alone foreign adversaries. Young people profess less and less desire to identify with their country, let alone fight for it. And whatever the talk of strategic adversaries, Western countries are still dependent on Russia, China and other competitors for basic and crucial goods, from oil to batteries. Should the new talk of military rearmament be welcomed, feared or perhaps even ridiculed? When the countries comprising the West seems to be in constant tension over Ukraine, free speech or attitudes to Chinese investment, is there even a West to speak of? Is it high time to get serious about the military and prepare for war? Or do we need to cool off?
