Truth is, Ron Paul's foreign policy agenda is straight out of the Democratic Party playbook. When Paul says that they attacked us on 911 "because we're over there", he's deadwrong. The Islamic religion opposes the US (western culture) because it opposes our way of life and our unalienable rights to freedom and liberty.
What is your evidence for that? I can give you lists of evidence to the contrary. Hundreds of terrorists have said time and again why they attack us and it is not what you just said. They intend to bring back the Caliphate. We support secular and less fundamentally Islamic regimes in the middle east. We have a western outpost in Israel. The regimes we support are very difficult to topple. We are the road block to their success in their goal of uniting the muslim nations of the world. That is why Israel is little satan and we are the great satan. Ron Paul is not incorrect as to the motivation of our attackers.
One can argue that Paul is wrong because we need to be in the middle east to prevent the extremists from toppling moderate regimes and reviving the Caliphate which would ultimately be more dangerous to us.
Specifically, the part about what the Dey of Algiers TOLD Jefferson and Adams in 1786 in London. The Islamofacists want to spread Islam and the word of Mohammad. They want all infidels to become Muslim. Nothing has changed in the 200 years since Jefferson or for that matter, since Mohammad walked the Earth some 14 centuries ago.
