There will never be a total WW2-like conflict so for the majority of people it is just a nice mind exercise.

But how many people are prepared to fight a war against propoganda? To defend freedom of speech? To defend opposite political views and opinions? It is scary but in the 1st and 2nd world you can still lose friends and even your job if you openly express your political views. People are afraid to express their views and it bothers me more than anything else.
