日俄战争是日本继中日甲午战争后在帝国扩张道路上发动的又一场决定性战争。在这场战争中,沙俄以极端轻视日本的姿态投入战争,屡遭败绩,最终不得不承认战争失利。其情报管理能力与情报保障能力水平低下是导致战败的主要原因之一,而日本因拥有全面情报战理念并在情报工作中花费巨资最终赢得战争的胜利,战后一跃跻身世界列强。 The Russo-Japanese War was yet another decisive war Japan launched on the road to imperial expansion following the Sino-Japanese Sino-Japanese War of 1894-1895. During this war, Russia, with its extreme contempt for Japan, was put into war and was repeatedly defeated. Eventually, he had to admit that the war was defeated. Its intelligence management capabilities and intelligence support capability were among the major causes of the defeat. Japan, after having possessed a full-scale intelligence warfare strategy and spending huge sums of money in intelligence work to finally win the war, plunged into the world powers after the war.
