Extremists, Insurgents, and Terrorists can not destroy America. Only we as American's can do that. So far we're doing a damn good job.
Islamic Fundamentalism wants to paint the west the same way
North Korean Propaganda does. They want people to choose a side. Their whole purpose is to sell the view that what they believe is correct. Children aren't born to be hate mongers and extremists. While some may be indoctrinated into it, most are drawn in by way of persuasion. Often those type of people tend to be poor and illiterate... No Extremist leaders, princes or sheik's or any of their family offer themselves up in a way that directly threatens their lives.
The ignorant perpetuate the kind of shit that these terrorists point to. Unfortunatly everyone always tends to focus on the negative and it works well when the example of the America these people are taught to hate are Good Ole Boy, Prejudice Spewing, Back Country fucks.
Terror Leader: "They hate Islam, See? They are all buddy-buddy with the Jews. They will rule you with Christianity, they want you to convert. You must fight!"
"Here's a suicide vest... I'm gunna be chillin other here. Say Hi to Allah for me, have fun with the virgins bro! Man You're Lucky! Gogogogo!"
