This sort of study of propaganda usually leads to the obvious, that most of what is said is propaganda, and as such does not actually give us much more certainty as to whether we will have to kiss our arses goodbye. All sides may at times make use of such fears in various different ways, and we should remain somewhat detached from the concept of kissing our arses goodbye unless indicators that arent just propaganda start flashing with greater intensity.
