I was just logging on to make a presentation at a European defence workshop, when Lord George Robertson’s ‘weapons not welfare’ speech broke in the media: "We cannot defend Britain with an ever-expanding welfare budget."
Like many interested in this sector, I wasn’t expecting the attack on government defence spending to come from the man who led the defence review. When you dig into the speech, his focus was on the pace of change and the delay in publishing the 10-year investment fund. As a former Defence Secretary, he clearly recalled his battles with the Treasury, accusing ‘non-military experts in the Treasury’ of ‘vandalism’. The Treasury has long been sceptical about increasing defence spending, not on ideological grounds but on grounds of deliverability. With some justification, they point to poor defence procurement, which is some way short of ‘vandalism’.
On the warfare versus welfare argument, the Chancellor has signalled her unwillingness to raise taxes to fund additional defence spending. She has warned that ‘difficult choices’ are required to increase defence spending, and other budgets may have to be cut, including welfare. Other ministers have been more explicit, including Wes Streeting, the health secretary, who suggested that welfare cuts could be required because it was critical to deal with the ‘challenge of the world we face’. The UK has already cut international development spending to fund additional defence spending, although there is a broader policy shift towards repurposing development aid.
It may sound like a straightforward trade-off, but in public spending terms, it is more complex. Welfare budgets have mandatory elements and can be demand-led, while defence spending is discretionary. In the US, this has been called the ‘Guns and Butter’ economic model. In the UK, defence is part of ‘final’ public expenditure, funding the armed forces’ pay and the weapons and equipment they use. This consumes money that can’t be allocated elsewhere in the budget and consumes a share of national output when the government spends it. In contrast, the welfare budget consists mainly of ‘transfer payments’ that shift income between households. Alan Shipman explains this in more detail.
Tony Benn famously said, “If we can find the money to kill people, we can find the money to help people.” This leads to the concept of military Keynesianism, which offers an increasingly tempting way for governments to combine the economics of full employment with the rhetoric of national security. The UK defence review implicitly invokes this to justify defence spending, highlighting the positive impact on jobs and local economies. The European Commission has proposed exempting total defence expenditure from EU fiscal rules for four years. Germany has already begun rearmament by suspending its constitutional debt brake.
