View figure at source: Costs of Major U.S. Wars

CBO chart comparing the federal costs of major U.S. wars, including wartime spending, debt-financing costs, and related veterans' obligations across conflicts

Provides the clearest visual foundation for the claim by showing how large-scale military interventions generate substantial federal expenditures and debt-related costs, while also making clear that fiscal costs do not by themselves establish a Treasury-yield effect

CBO chart showing the estimated relationship between federal debt held by the public and long-term interest rates, with historical data and projected or estimated interest-rate effects

This is the most direct visual for the proposed deficit-to-yield mechanism: higher debt is generally associated with upward pressure on interest rates, but the CBO presentation emphasizes uncertainty and conditionality rather than a mechanically fixed effect

Federal Reserve chart tracking the U.S. Treasury term premium and its decline over time, alongside factors such as global savings, lower inflation uncertainty, and demand for safe assets

Essential counterevidence to a one-directional war-borrowing story: long-term Treasury yields and term premia can fall or rise because of global demand for safe assets, inflation uncertainty, and financial conditions even when federal debt is increasing
