I thought it might be of interest here to compare the “Just War” concept with what is known in Arabic as “Jihad”…
First the “Just War” doctrine:
The strict conditions for* legitimate defense*** by military force require rigorous consideration. The gravity of such a decision makes it subject to rigorous conditions of moral legitimacy. At one and the same time:
- the damage inflicted by the aggressor on the nation or community of nations must be lasting, grave, and certain;
- all other means of putting an end to it must have been shown to be impractical or ineffective;
- there must be serious prospects of success;
- the use of arms must not produce evils and disorders graver than the evil to be eliminated. The power of modern means of destruction weighs very heavily in evaluating this condition.
These are the traditional elements enumerated in what is called the “just war” doctrine. The evaluation of these conditions for moral legitimacy belongs to the prudential judgment of those who have responsibility for the common good.

Now the concept of Jihad (struggle):
“
Religiously, jihad is the expending of utmost effort in upholding and defending justice,” said Sheikh Jaafar Idris, of the Saudi Arabian Embassy. Idris explained that he recognizes two kinds of jihad because there are two kinds of violations of justice: jihad with words against false beliefs, and jihad with the sword against acts of injustice. “The first is the basic and continuous jihad,” Idris said. “It was mentioned in the Qur’an very early in the history of Islam and at a time when Muslims were weak and even persecuted. God said to His Prophet, ‘Do not obey the kafireen (those who reject the truth) but wage jihad with it (the Qur’an) against them. [25:52]’”
