Lets look at the perils of communism.
To give an example of its horrors and how the public reacts to such a brutal system i shall quote paragraphs from James A Michener's book The Bridge at Andau, which covers the Hungarian revolt against communism in 1956.

In Hungary, Russia demonstrated that her programme is simple. Infiltrate a target nation, get immediate control of the police, initiate a terror which removes all intellectual and labour leadership, deport to siberia troublesome people (to the state), and then destroy the nation completely if the least sign of independence shows itself. This final step in the russian plan is what took place in Hungary.
From this point on it is difficult to imagine native born communists in italy of france, England or America trusting blindly that if they joined the russian orbit their fate would be any different.
At the first invitation from some dissident communist group inside the nation, russian tanks will roll in and destroy the capital city, terrorize the population and deport to slave labour camps in central asia most of the local communist leaders who organised the communist regime in the first place.
I write this to remind free men everywhere that there is no hope for a nation that allows itself to be swept into the orbit of international communism. There can only be one outcome: Terror and the loss of every freedom. This is what communism truly means.
