The clear difference between Muslims and the corrupt and deviant Jews and Christians is that Muslims are not ashamed of abiding by the rules sent down from their Lord regarding war and enforcement of divine law. So if it were the Muslims, instead of the Crusaders, who had fought the Japanese and Vietnamese or invaded the lands of the Native Americans, there would have been no regrets in killing and enslaving those therein. And since those mujahidin would have done so bound by the Law, they would have been thorough and without some “politically correct” need to apologize years later. The Japanese, for example, would have been forcefully converted to Islam from their pagan ways – and if they stubbornly declined, perhaps another nuke would change their mind. The Vietnamese would likewise be offered Islam or beds of napalm. As for the Native Americans – after the slaughter of their men, those who would favor smallpox to surrendering to the Lord – then the Muslims would have taken their surviving women and children as slaves, raising the children as model Muslims and impregnating their women to produce a new generation of mujahidin. As for the treacherous Jews of Europe and elsewhere – those who would betray their covenant – then their post-pubescent males would face a slaughter that would make the Holocaust sound like a bedtime story, as their women would be made to serve their husbands’ and fathers’ killers.
Furthermore, the lucrative African slave trade would have continued, supporting a strong economy. The Islamic leadership would not have bypassed Allah’s permission to sell captured pagan humans, to teach them, and to convert them, as they worked hard for their masters in building a beautiful country. Notably, of course, those of them who converted, practiced their religion well, and were freed would be treated no differently than any other free Muslim. This is unlike when the Christian slaves were emancipated in America, as they were not afforded supposedly government-recognized equal “rights” for more than a century – and their descendants still live in a nation divided over those days.
All of this would be done, not for racism, nationalism, or political lies, but to make the word of Allah supreme. Jihad is the ultimate show of one’s love for his Creator, facing the clashing of swords and buzzing of bullets on the battlefield, seeking to slaughter His enemies – whom he hates for Allah’s hatred of them. A religion without these fundamentals is one that does not call its adherents to fully manifest and uphold the love of the Lord.
Terrorism is probably about as old as states are.
So we do, and you can tell how useful their analyses are by how badly we're losing the War on Terror.
