This is merely a bullet point on the main article, but seems more-significant to me than the article’s main title, and has now been cited on a number of other news sites:
Iranian source tells Al Jazeera Iran sent a message to the US via Qatar saying that it does not seek regional war but adding that “the phase of unilateral self-restraint has ended”. It also warned any Israeli attack would be met with an “unconventional response” that includes targeting Israeli infrastructure.
This part irks me quite a bit. Like in the retaliation against the US after the assassination of an Iranian general invited to a diplomatic talk, Iran seems to avoid causing casualties to show strength, w.o. pushing for escalation. This is quite opposite to Israel who makes a point of indiscriminately slaughtering thousands of civilians in their actions, since their goal is to escalate into a great war in West Asia, where the US has to do their dirty work.
Israel has the US in its pocket, meanwhile there are plenty of hawks in the US who would love to go after Iran so there’s a huge imbalance. Iranian military responses are carefully choreographed to show defiance and stop short of escalation whilst Israel is running around doing whatever the hell it wants and ignoring the US.
