It's not radical Islam that worries the US -- it's independence
There's just no question that the United States was trying desperately to prevent the independence of South Vietnam and to prevent a political settlement inside South Vietnam. And in fact it went to war precisely to prevent that. It finally bombed the North in 1965 with the purpose of trying to get the North to use its influence to call off the insurgency in the South.
There's something deeply rooted in American culture. You can pretty much identify what it was. You take a look at the history. It was internal conquest. You had to defend yourself against what the Declaration of Independence, Thomas Jefferson, an enlightened figure, called the attacks of the "merciless Indian savages," whose known way of warfare was torture and destruction. Also you had a slave population, you had to protect yourself against them. You needed guns.
