威胁来自何方 三线建设究竟有没有必要?要回答这个问题,必然先要分析当时的国际形势,分析当时有没有遭受敌人突然袭击的可能性。如果有,这种战备决策就是必要的。至于战备搞到什么程度合适,则是次要问题。如果根本不存在这种可能性,那么三线建设的决策就是无的放矢,至少在当时国力状况下是超前的。 Is it necessary to start with the construction of the third line of threat? To answer this question, we must first analyze the international situation at the time and analyze the possibility of being attacked suddenly by the enemy. If so, this readiness strategy is necessary. As to what level of combat readiness is appropriate, it is a secondary issue. If such a possibility does not exist at all, then the decision-making on the third-line construction will be unobtrusive, at least under the current state of national strength.
