[W]hen God wishes to impose His will upon the His enemies, He chooses to do so by casting terror into their hearts….“Let not the Unbelievers think,” … - S. K. Malik

"National interest," concedes Bernard Brodie, "are not fixed by nature nor are identifiable by any generally acceptable standard of objective criteria. They are, instead, the product of fallible human judgement on matters on which agreement within the nation is unusually less than universal." Nor is the formulation of national interests, as is well-know to us today, necessarily or essentially governed by the consideration of peace. That being so, the logical outcome of the concept of national interests in the international system of today is tension and war, and not peace, harmony, justice and understanding. Indeed, national interest is: in train a vicious and never.ending cycle, the common denominator of which is 'war', not 'peace'.

As in the case of individuals, so inter-state relationship, war could only be waged for the sake of justice, truth, law and preservation of human society. The central theme behind the causes of wars, as spelt out by the holy Quran, was the cause of Allah. This cause manifested itself in different shapes and forms at different stages in the history of Islam. In the pursuit of this cause, the Muslims were first granted the permission to fight but were later commanded to fight in the Way of God as a matter of religious obligation and duty. The first Quranic revelation of the subject that granted the Muslims the permission to fight, read, "To those against war is made, permission is given (to fight) because they are wronged;—and verily, Allah is most Powerful for their aid. (They are) those who have been expelled from their homes in defiance of right,—(for no cause) except that they say, 'Our lord is Allah." Deliberating on the rationale behind the grant of the permission, the Book ruled, "Did not Allah check one set of people by means of another, there would surely have been pulled down monasteries, churches, synagogues and mosques in which the name of Allah is commemorated in abundant measure." At another occasion, the Holy Quran said, "Every time the kindle the fire of war, Allah doth extinguish it; but they (ever) strive to do mischief on earth. And Allah loveth not those who do mischief." What expectations did Almighty Allah place on that 'set of people' with whose help He planned to check the other? "(They are) those," the Book claims, "who, if we establish them in the land, establish regular prayer and give regular charity, enjoin the right and forbid wrong." A few months after the grant of the permission to fight in self-defence, came the divine command making war a religious compulsion and obligation. "Fight in the cause of Allah," it said, "those who fight you but do not transgress limits; for Allah loveth not transgressors." This revelation introduced new elements to the permissible causes of war. Fighting was to be in the cause of Allah. It was to be undertaken only against those who fought the Muslims first. During the conduct of war, the limits specified by God were not to be transgressed; those who did so were to incur divine displeasure.

When a believer sees that someone is trying to obstruct another believer from travelling on the road that leads to God, spirit of Jihād requires that such a man…be prevented from doing so and the obstacles…be removed, so that mankind may freely be able to negotiate its own path that leads to Heaven. To omit to do this is a culpable omission, if only because we…become passive spectators of the…forces imposing a blockade in the way of those who mean to keep their faith with God. Then ordinary wars which mankind has been fighting for…revenge or securing satisfaction of their desire of getting more land or more booty are not allowed in Islam. This is so because here the rule is, all striving must be for the sake of God….The wars in the theory of Islamic law are in the nature of an undertaking to advance God’s purpose on earth, and invariably they are defensive in character... It is a duty of a believer to carry forward the Message of God and to bring it to the notice of his fellow-men in handsome ways. But if someone attempts to obstruct him from doing so he is entitled, as a measure of defense, to “retaliate.” In other words, a Muslim has the right to fight anyone who stops him for spreading Islam and its message, and that is defined as a defensive measure.... In Islam war is waged to establish supremacy of the Lord only when every other argument has failed to convince those who reject His Will and work against the very purpose of the creation of mankind. Indeed, the person who goes to holy war virtually is offering testimony regarding the paramountcy and supreme authority of God’s law by giving up the most precious thing he has, namely, his life….Indeed the very word “Shahīd” which is roughly taken to mean as a martyr, literally signifies the idea that he has borne testimony as a witness that God’s law is supreme and anyone who attempts to obstruct the progress of those who are taking their path to God will be dealt with sternly—for that is the only way in which to restore and rehabilitate the authority of God on Earth...
Many Western Scholars have pointed their accusing fingers at some of the…verses in the Qur’an….As to them it is sufficient answer to make…that the defiance of God’s authority by one who is His slave exposes that slave to the risk of being held guilty of treason and such a one, in the perspective of Islamic law, is indeed to be treated as a sort of…cancerous growth on that organism of humanity….It thus becomes necessary to remove the cancerous malformation even if it be by surgical means (if it would not respond to other treatment), in order to save the rest of Humanity.
