The United States didn't have the intention of stopping anything.
They just wanted to infiltrate, see who controls what, and use it to their advantage when they want to.
You have to think back to World War 2, and ask yourself why the United States brought all of those German "scientists" to this country, when they already had technology and knew how to make atomic bombs. White supremacy has always been #1 on the United States' government list of agendas. Finding out what's going on with other groups and how to use it against them and have them kill each other is part of the FBI, CIA, Interpol, European Government plan. Help from the United States, Europe, and the West is just a harbinger of destruction for your country.
