核聚变能源被视为自人类分裂原子以来最重要的技术突破，具有改变全球战略格局的巨大潜力。这种能源不仅能提供安全、零温室气体排放的电力，且其燃料来源广泛，不受地缘政治或天气变化的限制。率先掌握这项技术的国家将获得无可估量的战略优势。

尽管科学家对实现核聚变的基本原理充满信心，但目前仍面临工程上的挑战，这部分归因于过去数十年间资金投入的起伏不定。现今，私人资金的投入虽已超过公共资金，但美国联邦政府对核聚变研究的资助依然不足且缺乏协调，这可能成为发展的一大阻碍。

相较之下，中国在核聚变领域的资金投入和基础建设布局大幅领先，并培养了数量远超美国的相关领域博士生。为了在竞争中保持优势，美国迫切需要发起如同曼哈顿计划般的国家级行动，提供充足的联邦资金，以彻底解决商业化道路上的技术难题。

Fusion energy is viewed as the most consequential technological breakthrough since the splitting of the atom, holding immense potential to reshape the global strategic landscape. This energy source not only offers safe, greenhouse gas-free electricity, but its fuel is also widely accessible and immune to geopolitical or weather-related constraints. The nation that first masters this technology will gain an incalculable strategic advantage.

Although scientists are confident in the fundamental principles of achieving fusion, significant engineering challenges remain, partly due to the boom-and-bust cycle of funding over past decades. Today, while private investment has surpassed public funding, the US federal government's financial support for fusion research remains insufficient and poorly coordinated, which could become a major obstacle to development.

In contrast, China has significantly outpaced the US in fusion funding and infrastructure planning, alongside training a far greater number of PhD students in the field. To maintain a competitive edge, the US urgently needs to launch a national effort akin to the Manhattan Project, backed by ambitious federal funding, to resolve the remaining technical hurdles on the path to commercialization.
