Bin Laden is a Saudi National, member of a particular tribe but not the Saud family. The Saud family is the royal family of SA, and they get all the wealth, which they proportion out to the other SA families/tribes as determined by tribal politics. The Wahabia tribe is the single most conservative Islamic tribe in the world, very anti-west, and even racist against other Muslims, considering themselves to be the purest Muslims. They are the bureaucrats of SA, they run all government positions at all levels, and control the flow of money. They funded Bin Laden's construction company all over SA properties for decades, and funnelled monies to his illigetimate activities even after the Saud family rejected Bin Laden's proposal to stand up an army to liberate Kuwait from Iraq.
Americans want to believe that nationality is important to these folks, but its not. Tribal/Family identity is all that matters. The Wahabi routinely run against the Saud family, but since they run everything and the Saud family enjoys all the benefits, they are never stopped. They got the Saud family to fund $1 billion a year in Muslim missions activity around the world, which they used to send Wahabi trained (anti-US) teachers to 2nd and 3rd world countries to make converts. In Africa they use our US $ to build the buildings, and buy the books, and use the Wahabis as the teachers, so we're paying for the next generation of US haters to learn how to be Wahabi ... thank you Clinton. Of course we're also paying Ethiopia to grow narcotics to sell to the Arab Peninsula ... thank you Bush.
I see the parallels from the OP as it relates to our President and his actions, but once it sets foot on the ground, the comparison stops. This is a COMPLETELY different thing that Vietnam.
