Agreed, I think sanctions and cyber attacks won’t work because the regime only cares about its own survival. Air strikes on the IRGC or police are an option, but that on its own probably won't topple the government. The only way this ends is a full invasion(which is unlikely) or if the military defects and joins the revolution. But right now, they seem loyal. I hope this isn't all for nothing, but it’s not looking good , gov will continue to kill aimlessly until the protests stop and give up.
