What I want to say is that after Israel attacked Iran, Iran generally does not retaliate immediately. Just think about it: did they retaliate right away after their leader was taken out last time? The so-called red revenge flag is mainly to soothe domestic sentiments.
I have seen some self-media explain why Iran is so aggressive; it's because they fear their regime being overthrown. It's a bit like what old Chiang said: you must first stabilize the internal situation before dealing with external threats.
Last time, they waited two weeks after the attack, so this time we don’t need to wait. The most important thing is that they informed Israel before launching the rockets.
What I want to say in the end is that you can just look at what the media publishes. To be honest, the news is really not as reliable as what self-media puts out.
On the 15th, they will continue negotiations with the U.S. regarding the Iran nuclear deal.
Also, don’t wonder why the news always writes some useless stuff; some things just can’t be published, and you have to learn to understand that. So, in the end, we can only look at some self-media and military bloggers for analysis of events.
