US Defense Spending charts as percentage of GDP since 1929 startling fact seen in this chart of Federal Reserve Bank of St Louis- that in 2026 we are seeing 1929-1937 levels of military spending to GDP ratio of 2-3% just before it jumped to 45% in 1940 in World War II. It is a cautionary tale not to spend too little (2-4% is a danger point), as lack of military modernization means a lot more spending soon after, almost 10 times that- 10 times 4% or 40%. Message to the US is not what Starmer and company are saying in Europe- it is that don't invite the existential crisis of 1940 again for western (US, EU, Canada, UK) and eastern democracies (India, Japan, Indonesia, Australia) by ignoring costs of military modernization. And 2-4% of GDP for military spending is not going to do this.
