They may win.
They have infested us in two way:

1. Immigration and founding of pro-Jihadist groups by policies established by "the politically correct" and lib-left governments.

2. A leftist press and media which is a direct result of corporate capitalism not capitalism (which I support). Corporate capitalists own the media and totally support a manipulable , non aggressive, non self-asserting population. Any such population that would defend itself against Islamic Fundamentalists would also be dangerous to established corporate power and would demand reforms in corporate totalitarianism and corporate monopolization.
This is the base root of the problem in our society. This group is not a unified cabal but a powerful elite of opportunists who drag on us like leeches and although our destruction will also be their destruction, they still wish to maintain their power and discourage any sense of self defence militancy in the population.

The result internally in our society the media is at war with itself and with us the real population.
