The dumb thing is pretending we are sinless in our relationship with the middle east.
Okay, let's start at the beginning, the use of the word "Terrorist". One man's terrorist is another man's freedom fighter. When Osama Bin Laden was in Afghanistan killing Russians, Ronald Reagan gave him a shitload of weapons and called him a "Freedom Fighter".
When he attacked the WTC, he gave three grievances against the US. Our support of Israel, our occupation of Saudi Arabia, and our use of economic warfare against Iraq killing hundreds of thousands of people. It doesn't justify the use of violence against civilians, but these were not religious goals. These were fairly legitimate policy complaints.
In short, the "Terrorists" are largely a problem we have created. Pretending that they want to conquer the world for their religion or hate our freedoms or some such shit is like something you would read in a comic book, but it doesn't reflect reality.
Hey, did you notice the Terrorist never attack Japan? Why do you think that is? Oh, that's right. Japan minds it's own fucking business.
