They want the US to fail because they are full of hate. The hate rightfully should be attached to themselves and their life choices. That they cannot bear. Ergo, this hate is projected on ideals, people, philosophies they know they cannot accept, match or attain.
What is pricelessly ironic is that most of those engaged in this intentional destruction of American values are the very same ones who pride themselves on their ability to create.
They also seem to think that they would somehow be immune from future attacks on America. If the nation goes down, we all would go down. When they want America to fail, they somehow think this doesn't include them. It's lunacy.
