I am hoping for some help with this question.
I am not looking to debate whether or not Communsim is right/wrong or effective/ineffective etc.
All I was wondering was whether Marx and/or Engels acknowledged that Communism needed to spread across the globe in order to be realized, or if that was a latter Trotsky addition.
Obviously if you don't have a central authoritative governement, then you do not have a cohesive standing army and leave yourself wide open to attack - especiallt in the post industrialized era of planes, bombs and distance warfare.
Trotsky openly acknowledged this - I want to know if he was the first.
