In her article, Carol Roth highlights the significant fiscal challenges facing the U.S. government, noting that the current debt-to-GDP ratio has reached around 120%. This level is alarming as it aligns with those seen in emerging markets that are experiencing a financial crisis. Roth points out the critical role of the U.S. dollar as a reserve currency and the importance of the country's economic stability, which currently allows the U.S. to sustain its large deficits—deficits that are usually only present during wartime or recessionary periods.

Roth further argues that the government's interest expenses on national debt have now surpassed defense spending, a concerning trend echoed by historian Niall Ferguson. Ferguson's Law suggests that a nation spending more on debt servicing than on defense may lose its status as a global power. Roth warns that the rising interest rates are compounding this issue, increasing the cost of servicing debt at a time when the U.S. is already struggling with an extensive debt load that requires refinancing, thereby deepening the fiscal crisis.

Overall, Roth implies that Trump's apprehensions regarding interest rates are justified, as they hold grave consequences for future fiscal policy and the capacity for national defense. If the trend continues, it might jeopardize the U.S.'s position as a leading global power, ultimately affecting both domestic and international economic stability.
