Whatever problems may or may not be happening within the Muslim Brotherhood, if there is division among their ranks, etc; in my opinion, the real issue is incompetence and ineffectiveness.
I don’t see the value in uniting behind a strategy that doesn’t work. So if they are united or divided, I don’t really see the relevance; either way, they have not produced a plan of useful resistance.
Rather, these internal problems are endemic to large organizations, and highlight the necessity of independent action.
