Was the US justified in containing communism?
They sure were. Communism was and is (China/North Korea) an
extremely persecuting style of governing. Half the world it seemed,
at times, was under one red flag or another. What started out as an
attempt in Russia to make everyone equal, with equal rights, soon
deteriorated into the rich at the top getting everything; and the
ordinary people getting the scraps. Secret police forces came to
life in communist countries to protect "the system" and yet got so
bad they ended up murdering anyone they thought was "anti-system".
That wasnt going to happen to western Christian democracies.
