Revolutions do't start with a leader that decides to start one. They start with a bunch of small groups that somehow finds a leader..
Castro didn't start the Cuban revolution, he just managed to pull all the groups under his flag.
Right now there is no clear leader. If and when there is, the real shooting begins.
Exactly. In Cuba, there was a political goal. Something all these groups agreed was so important that they would all work together to create it.
These anarchists are the exact opposite. They have no goals to create anything, nothing they want to achieve, they just want to burn and vandalize whenever the mood strikes them.
And yes, some of them will be manipulated by those who do have a political goal, no question about that, but again, minority, and no civil war coming from that front.
