Strive hard against the unbelievers and the hypocrites and be unyielding to them; and their abode is hell, and evil is their destination. Quran 9:73And, if history is any guide, religious wars have been the bloodiest in human history. The contention that all wars eventually should end may not be applicable this time. This one is different; with new generations of Islamists willing to kill themselves in order to destroy the infidels, it may take generations, centuries, to end, especially given the high birth rate of the enemy. At this juncture it is impossible to predict how it may end.
In previous world wars the winner typically out-produced the loser. During the Second World War Americans were losing, on average six Sherman tanks for every German Tiger tank lost. But at the same time, American industry was manufacturing six Sherman tanks faster than Germans could produce one Tiger. Americans were producing more bombers than Germans were shooting down, and that was true for every other piece of military equipment. The United States, despite heavy losses at Pearl Harbor, not only replaced those losses in short order but also built a greater and more modern fleet than that of the Japanese. Imperial Japan and Nazi Germany were facing the unlimited industrial capabilities of the United States, further multiplied by the unlimited human resources of the Soviet Union. There was not a chance that the Axis powers could possibly win the war; they were out-produced and out-manned. The longer the war went on, the weaker Germany and Japan became.
