But, wait, this is Iran ran by the revolutionary guards... What did anyone expect? Was it right to tell this people - help is on the way, when there was none?
Sorry, downvote as much as you like, but I'll reiterate - the brave Persian people will do it better next way, as they now know tis entirely up to them, no help comes. And they are super brave to do what they did, where did you exactly got wrong what I wrote??
Honestly - the weakest point is and will always be communication, once you loose it you fire in the dark. Like many other revolts, this also was heavily dependent on internet coordination, means controlled by the government.
So perhaps being able to organise is much more challenging to the status quo than having a pistol in every house. I would also argue 21st century revolutions are perhaps a little different from others before.
I can easily imagine a very massive cyber revolt where communications are brought to a standstill for the ruling elite. But while imaginable is hard to enact in practice and someone else in the comments noted many top Iranian officials had an IT or engineering backgrounds which makes them better prepared and the whole effort much more challenging.
