现代战争、策略与武器系统正以极快的速度转变。乌克兰大量使用廉价无人机与无人艇成功摧毁高价战舰，显示出低成本武器在战场上的颠覆性威力，这对美国及西方国家长期以来的军事主导地位构成了严峻挑战。

人工智慧（AI）的快速发展与军事化应用，正在进一步缩小美国与其潜在对手之间的技术差距。中国的AI公司正以极低的成本复制美国顶尖AI模型的进展，使得未来的AI军备竞赛变得不可避免且难以监管。

面对地缘政治与科技的剧烈变革，各国国防预算面临艰难抉择。与其维持昂贵但脆弱的传统大型装备，欧洲与西方国家更应将资源集中于无人机技术、海底管道防护，以及防范来自中俄等国的低烈度持续性威胁。

Modern warfare, strategy, and weapons systems are transforming at an extraordinary speed. Ukraine's successful deployment of cheap drones and kamikaze boats to destroy expensive warships demonstrates the disruptive power of low-cost weaponry, posing a serious threat to the long-standing military dominance of the US and the West.

The rapid development and military application of artificial intelligence (AI) are further narrowing the technological gap between the US and its potential adversaries. Chinese AI firms are replicating the progress of top US models at a fraction of the cost, rendering a global AI arms race both inevitable and difficult to regulate.

In the face of drastic geopolitical and technological shifts, nations must make difficult defense procurement choices. Instead of maintaining expensive yet vulnerable traditional military assets, Western countries should focus their resources on drone technology, undersea infrastructure protection, and countering persistent low-intensity threats from adversaries like Russia and China.
