如果列一份"必保名单"，湖北宜昌的顺位，可能比某些沿海一线城市还要高。 我们惯性思维里，城市是按房价以及GDP排座次的。但在战争逻辑下，"含金量"这时候得让位给"含狠量"。 别看不起那些平时不显山露水的三线城市，真到了生死存亡的时刻，它们可能是国家最后的底牌。 回答是肯定的：有，并且必须有。 为什么？就因为三峡大坝。 宜昌是标准的三线城市，平时大家去旅游，看的是高峡平湖。但在战略家眼里，这里是长江的"七寸"。这是一把悬在长江中下游头顶的达摩克利斯之剑。 下游是谁？那是武汉、南京、上海，是整个中国的经济大动脉。一旦宜昌失守，大坝出了问题，那不仅仅是洪水滔天，而是整个长江经济带瞬间瘫痪。 所以，现代战争手段再怎么升级，针对宜昌的防御级别绝对是天花板级的。 死保宜昌，本质上就是死保半个中国。 这不是经济账，是生存账。 大家对绵阳的印象是什么？四川第二大城市？米粉好吃？ 拿绵阳来说，如果你去过，会发现这就一安逸的小城。但在国际军事观察员眼里，绵阳还有一个代号——中国科技城。 这里藏着中国最硬的"骨头"。 回看历史，当年的"三线建设"，无数科研院所往山沟里钻，绵阳就是重中之重。这里有中国工程物理研究院（九院），那是咱们 ...
