Netanyahu used that line on Tim Russert after Russert said "well... people don't think the West is under threat by Islamic terrorists". Netanyahu responded: "Well, that's because their understanding of history goes to breakfast." Which I thought summed it up pretty well.
People (not all people... so, I'm not making any judgments or being condescending to anyone... I'm explaining Bibi's thought here. I agree with Bibi, but no one take offense... I'm not looking for an argument) who do not realize the threat the West finds itself under probably do not have a clear understanding of the history of the last 100 years. Their understanding of the conflict goes back so far and stops. That's why they can say... "nah, there's no threat..." If you understood the whole history of Islam... and the Crusades, and the colonization of the Middle East, and the Zionists, and the Israeli/Arab conflict, and the defeat of the Soviets in Afghanistan, and 10 years of non-retaliation of America on terrorism. If you understand what Resolution 242 says and how it has been perverted by the media... etc. Then you might have different opinion of whether we were under threat (or not).
After 9/11, when I began to study I had a very simplistic view of why we were attacked. My understanding of history went to breakfast (very shallow). As I began to learn, my understanding grew. The deeper I delved the more I'm convinced it is a clash of civilizations.
I hope that clarifies it a bit more. I will get that kit to you in the mail.
