反叛者自2001年以来一直进行游击战争。

The rebels have waged a guerrilla war since 2001.

《牛津词典》

我们必须牢记，就像伊拉克一样，阿富汗不是一场经典的消耗战——它是一场反游击战争，而且它不能仅仅依靠军事手段来取得胜利。

We must remember that Afghanistan, just as Iraq, is not a classic war of attrition—this is counter-insurgency, and it will not be won by military means alone.

就是游击战争控制的地方，如果不粉碎敌人的进攻，不战胜敌人，自己控制的地方就要变成敌人控制的地方，也无从建立根据地。

Unless we repulse the enemy's attacks and defeat him, even places held by the guerrillas will come under enemy control, and then it will be impossible to establish base areas.
