近期，多家美国主流媒体指出，美国当前面临的最大威胁并非来自外部对手，而是其不断膨胀的国家债务。据美国财政部数据显示，截至2024年，美国联邦政府债务总额已突破34万亿美元，占GDP比重超过120%。这一数字不仅创下历史新高，也引发了市场对财政可持续性和美元长期信用的担忧。分析人士认为，高额债务限制了政府在应对经济衰退、公共卫生危机或地缘政治冲突时的财政灵活性。同时，利息支出持续攀升，2023财年联邦净利息支出已超过7000亿美元，成为仅次于社会保障的第二大政府支出项目。若利率维持高位，未来利息负担将进一步加重，可能挤压教育、基建和国防等关键领域的投入。此外，政治极化使两党难以就财政改革达成共识，预算僵局频发，加剧了市场不确定性。有评论指出，若不采取有效措施控制赤字和债务增长，美国或将面临主权信用评级下调、融资成本上升甚至债务违约的风险。因此，美媒普遍呼吁将债务问题视为国家安全层面的战略挑战，而非单纯的经济议题。
Recently, several major U.S. media outlets have argued that America’s greatest threat no longer comes from external adversaries but from its own ballooning national debt. According to data from the U.S. Treasury, as of 2024, the federal government’s total debt has surpassed $34 trillion—over 120% of GDP—setting a new historical record and raising concerns about fiscal sustainability and the long-term credibility of the U.S. dollar.Analysts warn that such high debt levels severely limit the government’s fiscal flexibility in responding to economic downturns, public health emergencies, or geopolitical crises. Moreover, interest payments are soaring: net interest expenses exceeded $700 billion in fiscal year 2023, making it the second-largest federal expenditure after Social Security. If interest rates remain elevated, this burden will grow further, potentially crowding out critical investments in education, infrastructure, and defense.Compounding the problem is political polarization, which has prevented bipartisan consensus on fiscal reform and led to repeated budget standoffs, increasing market uncertainty. Some commentators caution that without effective measures to curb deficits and debt growth, the U.S. could face credit rating downgrades, higher borrowing costs, or even a debt default. Consequently, many U.S. media sources now frame the debt crisis not merely as an economic issue but as a strategic national security challenge.
