Today humanity is being challenged. Unthinkable atrocities take place on daily basis. There is an evil force at work that aims to destroy us. The agents of this evil respect nothing; not even the lives of children. Every day there are bombings, every day innocent people are targeted and murdered. It seems as if we are helpless. But we are not! The ancient Chinese sage Sun Zi said, "Know your enemy and you won't be defeated". Do we know our enemy? If we don't, then we are doomed. Terrorism is not an ideology, it is a tool; but the terrorists kill for an ideology. They call that ideology Islam. The entire world, both Muslims and non-Muslims claim that the terrorists have hijacked "the religion of peace" and Islam does not condone violence. Who is right? Do the terrorists understand Islam better, or do those who decry them? The answer to this question is the key to our victory, and failure to find that key will result in our loss and death will be upon us. The key is in the Quran and the history of Islam. Those of us, who know Islam, know that the understanding of the terrorists of Islam is correct. They are doing nothing that their prophet did not do and did not encourage his followers to do. Murder, rape, assassination, beheading, massacre and sacrilege of the dead "to delight the hearts of the believers" were all practiced by Muhammad, were taught by him and were observed by Muslims throughout their history. If truth has ever mattered, it matters most
