一劍飄塵：援助烏克蘭，美國為什麼要承擔更多責任

反賊網注：世界應該援助烏克蘭的主要原因是因為烏克蘭是在打一場反抗侵略的戰爭。本文則主要講為什麼美國應該承擔更大比例的援助。 关于美国为什么要支持乌克兰，我这次写得长一点，希望能解释清楚。

关于欧洲对乌克兰支持力度不及美国的讨论引发了广泛关注。然而，深入分析后可以发现，这种比较并未充分考虑双方在国际责任、经济实力和军事能力方面的差异。

1. 国际责任的分担：美国的全球领导角色

美国在全球事务中扮演着主导角色，其军事和经济影响力使其承担起维护国际秩序的责任。欧洲国家普遍承认美国的霸权地位和美元的国际货币地位，这意味着美国在全球安全事务中应承担更大的责任。因此，美国对乌克兰的支持力度更大，符合其作为全球领导者的角色定位。例如，北约的集体防御原则中，美国的行动往往是决定性的。如果美国放弃对乌克兰的支持，基本上就相当于放弃了这种领导地位。短期看，一年节省几百亿，但这种软实力（美元、全球领袖）的损失，是几百倍于这种经济节省的。

1. 经济实力对比：人均GDP的差异

美国的人均国内生产总值（GDP）显著高于欧洲国家。根据国际货币基金组织的数据，2023年美国的人均GDP约为7万美元，而欧盟国家的平均人均GDP约为4万美元。这种经济实力的差距直接影响了各国对外援助的能力。美国更强的经济实力使其能够提供更多的援助资金，而欧洲国家在经济能力有限的情况下，已尽力提供支持。例如，德国和法国虽然在提供援助，但其经济负担相对较高。

1. 军事能力对比：军费开支和军备水平

美国的军费开支远超欧洲国家。2022年，美国的军费开支占全球军费的39%，而欧洲国家的军费支出总和仅占全球的约20%。这种军事投入的差异导致美国在武器装备、军事技术和全球投送能力方面具有明显优势。因此，美国能够为乌克兰提供更多的军事援助，而欧洲国家在军备水平相对落后的情况下，已尽其所能提供支持。例如，波兰、英国等国虽然提供了武器，但规模和技术水平与美国相比还是有差距。

1. 武器援助与美国经济：利用库存落后武器

美国对乌克兰的援助很大一部分是武器支援，而这些武器中，很多是库存的落后武器。这些武器不需要进一步的生产成本，且在使用前需要拆卸和维护，这实际上为美国的军工企业带来了一系列的经济效益。例如，据报道，美国向乌克兰提供的武器中包括大量的过期或即将过期的弹药和装备，这些物资的处理成本原本会很高，但现在反而通过援助变相清理了库存，同时创造了新的就业机会和经济活动。2023年，美国国防部的数据显示，超过60%的援助物资是来自现有库存，这直接减少了储存和处理这些过时武器的成本，同时促进了军工企业的新订单和生产活动，间接支持了美国经济。相对来说，欧洲并没有美国这样强大的军工企业。支持乌克兰，欧洲并不会像美国这样，取得经济上的利益。

I wrote a longer article this time to explain why the United States supports Ukraine. I hope I can explain it clearly.

• The discussion about Europe's support for Ukraine being less than that of the United States has attracted widespread attention. However, after a deeper analysis, it can be found that this comparison does not fully take into account the differences between the two sides in terms of international responsibilities, economic strength and military capabilities.

1. The Distribution of International Responsibilities: America's Global Leadership Role

The United States plays a dominant role in global affairs, with its military and economic influence requiring it to shoulder the responsibility of maintaining international order. European countries generally acknowledge America's hegemonic position and the global status of the U.S. dollar, which means that the U.S. is expected to take on greater responsibilities in global security matters. Therefore, America's greater support for Ukraine aligns with its role as a global leader. For instance, in NATO's principle of collective defense, U.S. actions are often decisive. If the U.S. were to abandon its support for Ukraine, it would essentially be abandoning its leadership role. In the short term, this could save billions annually, but the loss of soft power—such as the influence of the U.S. dollar and its global leadership status—would outweigh these savings by hundreds of times.

1. Economic Strength Comparison: The Per Capita GDP Gap

The United States has a significantly higher per capita Gross Domestic Product (GDP) compared to European countries. According to the International Monetary Fund, the per capita GDP of the U.S. in 2023 was about $70,000, while the average per capita GDP of European Union countries was about $40,000. This disparity in economic strength directly affects each country's ability to provide foreign aid. America's stronger economic power allows it to contribute more funds, while European countries, despite their limited economic capacity, have already done their best to provide support. For example, although Germany and France have offered aid, their economic burdens are relatively higher.

1. Military Capability Comparison: Defense Spending and Armament Levels

The United States' defense spending far exceeds that of European countries. In 2022, U.S. defense spending accounted for 39% of global military expenditures, whereas European countries collectively accounted for only about 20%. This difference in military investment gives the U.S. a clear advantage in weaponry, military technology, and global deployment capabilities. As a result, the U.S. can provide more military aid to Ukraine, while European countries, with their relatively lower levels of military readiness, have already done their utmost to support Ukraine. For instance, countries like Poland and the United Kingdom have supplied weapons, but the scale and technological sophistication of their contributions pale in comparison to those of the United States.

1. Weapon Aid and U.S. Economic Benefits: Leveraging Obsolete Stockpiles

A significant portion of U.S. aid to Ukraine consists of weaponry, much of which comes from existing stockpiles of outdated equipment. These weapons incur no additional production costs and often require dismantling or maintenance before use, creating economic benefits for U.S. defense industries. For example, reports indicate that much of the U.S.-supplied aid includes expired or soon-to-expire ammunition and equipment, which would otherwise entail high disposal costs. Instead, through this aid, these stockpiles are effectively cleared while generating new employment opportunities and economic activities. According to 2023 data from the U.S. Department of Defense, over 60% of the aid provided came from existing stockpiles, directly reducing the cost of storing and handling these obsolete weapons while stimulating new orders and production activities for defense companies. Comparatively, European countries do not possess defense industries as powerful as those of the United States. Supporting Ukraine does not yield the same economic benefits for Europe as it does for the U.S.
