defensive warfare meaning in English

防御战

However , defensive warfare , which is passive in form , can be active in content , and can be switched from the stage in which it is passive in form to the stage in which it is active both in form and in content
然而防御战是能够在被动的形式中具有主动的内容的，是能够由形式上的被动阶段转入形式上内容上的主动阶段的。
If we should use " protracted defensive warfare on interior lines " as the principle for campaigns and battles too , as we did at the beginning of the war of resistance , it would be totally unsuited to the circumstances in which the enemy is small while we are big and the enemy is strong while we are weak ; in that case we could never achieve our strategic objective of a protracted war and we would be defeated by the enemy
如果战役和战斗方针也同样是“内线的持久的防御战” ，例如抗战初起时期之所为，那就完全不适合敌小我大、敌强我弱这两种情况，那就决然达不到战略目的，达不到总的持久战，而将为敌人所击败。
