本周推荐：《战争广告代理商：情报操纵与波黑战争》

作者: [日]高木彻

译者: 孙逢明

推荐: 小编1号

这是一本比较少见的看的时候觉得有点无聊但是合上书之后突然后背冒冷汗的非虚构作品。

这是真实发生过的事情。同样的事情现在正在发生，而且是同时在至少两个战地发生。

1992年在欧洲发生的战争，在1998年的时候突然与每一位中国人息息相关。

1992年的宣发手段，在2024年依然每天在电视里出现。

这本书让你从电视机和手机信息流的接受者，突然把你拽到了新闻制作的现场，又把你的头拧向了策划国家战争级别宣发的编剧讨论现场。

如果你真的（某一刻突然地）理解了本书描述的事情，你可能会再也回不到看这本书之前看世界的角度了。这让我我需要提醒读者，避免陷入历史虚无主义。
