One underlying common theme in the various versions of the three presidents' foreign policy doctrines is that Terrorism is un-Islamic.

President Clinton.  Address to the Nation, August 20, 1998:

Islam [is] the faith of hundreds of millions of good, peace-loving people all around the world, including the United States. No religion condones the murder of innocent men, women and children. But our actions were aimed at fanatics and killers who wrap murder in the cloak of righteousness; and in so doing, profane the great religion in whose name they claim to act. 

President Bush. Address before the Islamic Center of Washington, D.C. September 17, 2001:

The face of terror is not the true faith of Islam. That's not what Islam is all about. Islam is peace. These terrorists don't represent peace. They represent evil and war. When we think of Islam we think of a faith that brings comfort to a billion people around the world. Billions of people find comfort and solace and peace. And that's made brothers and sisters out of every race -- out of every race.

President Obama. Responding to a question after his address at  Mumbai's St. Xavier's college. November 7, 2010.

" ... Islam is one of the world's great religions. More than a billion people practice Islam and an overwhelming majority view their obligations to a religion that reaffirms peace, fairness, tolerance. I think all of us recognize that this great religion in the hands of a few extremists has been distorted by violence,"

The Clinton-Bush-Obama doctrine is coin of the realm in England also. Right after the recent murder and beheading of a British solider by two Muslim men, British Prime Minister David Cameron immediately issued this statement: "This was not just an attack on Britain and on the British way of life, it was also a betrayal of Islam and of the Muslim communities who give so much to our country. There is nothing in Islam that justifies this truly dreadful act."

Nothing in Islam? Un-Islamic?

Bukhari:V4B52N220 "Allah's Apostle said, 'I have been made victorious with terror.'"

Qur'an:8:12 "I shall terrorize the infidels. So wound their bodies and incapacitate them because they oppose Allah and His Apostle."

Qur'an:8:57 "If you gain mastery over them in battle, inflict such a defeat as would terrorize them, so that they would learn a lesson and be warned."

Ishaq:326 "If you come upon them, deal so forcibly as to terrify those who would follow, that they may be warned. Make a severe example of them by terrorizing Allah's enemies."

Poor Muhammad. I guess he just didn't have a clue about the religion he founded.

Bukhari:V4B52N220 "Allah's Apostle said, 'I have been made victorious with terror.'"

Qur'an:8:12 "I shall terrorize the infidels. So wound their bodies and incapacitate them because they oppose Allah and His Apostle."

Qur'an:8:57 "If you gain mastery over them in battle, inflict such a defeat as would terrorize them, so that they would learn a lesson and be warned."

Ishaq:326 "If you come upon them, deal so forcibly as to terrify those who would follow, that they may be warned. Make a severe example of them by terrorizing Allah's enemies."
