The writer here has attempted to refute the Conservative's arguments. However, as I mentioned in my comment below the article I don't understand why he singles out the Conservatives and the Libertarians but does not include the liberals of "free market liberal democracy" and their defence of the system nationally and internationally with its implications from wars to exploitation and preserving the status quo albeit with what they call "reforms" . "Can democratic socialism set us free?"
“The West won the world not by the superiority of its ideas or values or religion (to which few members of other civilizations were converted) but rather by its superiority in applying organized violence. Westerners often forget this fact; non-Westerners never do.” —Samuel P. Huntington, The Clash of Civilisation and the Remaking of the World Order, 1996, p. 51
