To answer your question, No I do not think this engineered virus, Swine Flu, is the end of humanity - but I do believe that it will do what it was created to do and that is to kill millions of people.
There are people in our world who have the money and the power to control their own lives. Once you get that kind of power, it in itself is never enough.
As a result they now seek to control you and me. But more specifically because they consider us as "useless eaters" of the world's quickly depleting resources, we are expendible so that their elitist children can inherit more of those resources.
I know its rather 'out there' to think that but as I have studied this world for a long time now and I definitely see a dark hand at work in the way our world is being run.
Don't you?
