根据日本《每日新闻》网站2月21日的报道，美国最高法院裁定特朗普政府推行的对等关税无效后，令人惊讶的是，日本仍然没有敢于撕毁 与美国签订的日美投资协议。众所周知，为了让美国减轻对等关税，日本当时不惜同特朗普签订了一份让人心生疑虑的协议，代价高达 5500亿美元。然而，如今对等关税被判无效，本该是个喜讯，意味着日本不必再承担这笔庞大的费用，但它依然不敢轻易撕毁协议。这背 后的真正原因，显然并不是因为日本富得无处花钱，而是有着四个深层的考虑。 再者，5500亿美元的投资，最终无论如何日本都要付出。即便是撕毁协议，也不能改变这一现实。日本如今走向右转已是无法避免的趋 势，但这并不是日本单方面可以控制的，光是社会氛围的转变并不足够，关键在于它能否扩展军备，增派军队，并提升尖端武器的生产能 力。而这一切，没有美国的认可，根本无法实现。日本的军事工业在很大程度上依赖美国，尤其是日本的航空自卫队，其研发的F2战斗机 几乎就是美国F-16的日本版，而这些战斗机的关键零部件几乎全由美国供应。日本海上自卫队和陆上自卫队的状况也类似。没有美国的技 术支持，日本根本无法独立研发和生产如此高端的军事装备。5500亿美元，实际上是买路钱 ...
