About Socialists being Elites, removed from people's sufferings, is incorrect. For example, your Pakistani Progressive music band, Laal, has a song called
Inqalab, about bonded laborers in South Asia.
About bloodshed, it could have, could have, turned out to be a bloodless coup, like Gaddafi's coup in Libya. I believe so because some of the plotters were senior, if I am not wrong, and could have commanded the respect of the junior staff as to not present resistance.
About Pakistan not ready for Socialist revolution... well, any Socialist revolution and governance is an experiment, its results not known until that experiment is carried out.
